27 Clinical Trials for Various Conditions
The goal of this clinical trial is to learn if a pain medication called liposomal bupivacaine (brand name EXPAREL®) with epinephrine will provide better pain control, increased activity, and reduced use of opioids compared with the standard treatment for patients age 6 years and older with cleft lip and palate who have had an alveolar bone graft surgery. Investigators will look at: * pain scores at hip and jaw sites * opioid use in amount and frequency * scores on activity questionnaires Researchers will compare the results of these items with those of patients who had the standard treatment of bupivacaine with epinephrine.
The purpose of this trial is to evaluate if the use of Bone Morphogenic Protein(BMP)/Demineralized Bone Matrix (DBM) versus the use of autologous Iliac Crest Bone Graft (ICBG) will result in an increase in total cost effectiveness for patients undergoing alveolar bone graft (ABG) for Cleft Lip and Palate (CLP) and to see if patients who are treated with DBM/BMP will have reduced post-operative pain scores,reduced operative times,and similar rates of bone healing compared to conventional ICBG.
The main purpose of the study is to measure and localize immediate post extraction changes i.e. socket expansion versus no width change along the socket wall and identify whether the immediate post-extraction ridge width condition (expansion or no change) is a determinant of buccolingual ridge width and height changes 4 months following extraction and ridge preservation.
The primary investigators in this study plan to investigate serum concentrations of ropivacaine in pediatric patients who already receive as standard of care a continuous wound catheter after an iliac crest alveolar bone graft harvest for completion of a previous cleft palate repair. The goals of this study are 1) to determine serum concentrations (free, unbound) of ropivacaine 2) To evaluate pain scores during the perioperative period to determine efficacy of wound catheters for postoperative analgesia for iliac crest bone graft harvest.
The purpose of this study is to evaluate clinically, histologically and radiographically the healing of extraction sockets with Zimmer's Puros® allograft compared to creos™ (creo™ Nobel Biocare,), a low-cost allograft material, 90 days following exodontia.
The study will be done to see if Implant placement and simultaneous grafting using alloderm alone will result in the same facial ridge contour and soft tissue thickness as alloderm plus bovine derived xenograft. Is the facial soft tissue contour and thickness for alloderm plus bovine derived xenograft is significantly increased compared to alloderm alone.
Dental implant placement and simultaneous grafting using one layer gum graft will result in the same facial ridge contour and soft tissue thickness as one layer of gum graft plus bone graft.
This study is intended to provide statistically robust evidence that Symbios Demineralized Cortical-cancellous granule mix, Symbios OsteoGraf LD-300, and OsteoGraf/N-300 combined with Symbios OsteoShield Collagen Resorbable Membrane can adequately support the alveolus during ridge augmentation procedures, reducing the dimensional changes of both the alveolus and the overlying soft tissues. Additionally, a comparison between each material will be made, providing further evidence of each materials' ability to preserve the alveolus. It is intended to define in objective terms the response of the hard and soft tissues to ridge augmentation.
The purpose of this study is to compare two different bone graft materials (freeze-dried bone allograft, FDBA and collagen-enriched bovine xenograft, CEBX) that are routinely used for preserving the remaining bone after extraction of an anterior tooth, and before placing a dental implant. Patients will be randomly assigned to either group (flip of a coin) One group will receive FDBA material and the other group will receive CEBX (cow) material. The study aims to examine the following main questions: * Potential differences in linear radiographic horizontal (HRD) and vertical (VRD) ridge dimensional changes between groups after 16 weeks of healing * Other clinical information of the treated areas and information regarding the esthetics of the dental implant that will subsequently be placed at the edentulous site as well as patient satisfaction with the treatment, will be evaluated. The study will include 7 study visits. Study procedures will take place during the same visits as the standard of care treatments (tooth extraction and bone graft, dental implant placement, crown installation and follow-ups). Clinical information from these standard of care visits will be used for the current research study, such as: * Demographic information * Clinical information from intraoral photographs * Radiographic information from cone beam computed tomography and periapical radiographs.
The purpose of the study is to compare a new grafting material for alveolar ridge preservation to a commonly used and well studied material. Alveolar ridge dimensions as well as histology will be compared.
The primary aims of this study are to compare, after 4 months, the clinical and histologic results of a combination demineralized/mineralized putty allograft vs. synthetic calcium phosphosilicate (CPS) putty alloplast graft utilization in socket preservation procedures. A regenerative tissue matrix membrane will be used to cover each graft lying below the flap.
The goal of this study was to compare, clinical and histologically, the use of the suine collagen matrix (Mucograft Seal \[MS\], Geisthlich®) and the free gingival graft (FGG) for the alveolar sealing after inserted bone graft biomaterial. It was included 18 patients with tooth referred to extraction (maxilar incisives, canines, or pre-molars) which were randomly divided in 2 groups, according to the material for alveolus sealing: control (FGG) and test (MS). After the minimally traumatic extraction, all the alveoli were filled with bovine mineral matrix (Bio-Oss®), and the material for alveolar sealing were positioned and stabilized with sutures. The follow-up (clinical and photographic) happened on the immediate post-operatory period, and with 3, 7, 15, 30, 60, 90, and 120 days. After 120 days, before implant placement, tissues samples were obtained with a 3.5mm punch scalpel for histological analysis. Qualitative information related to the patient's perception considering the treatment were collected.
The bone grafting materials currently used in dentistry are autografts, allografts, xenografts, and alloplastic grafts. Among these different types of bone graft materials, autografts are considered to have the most predictable results due to its properties of osteogenesis, osteoinduction and osteoconduction. However, bone autografts are rarely used due to the high morbidity associated with harvesting the bone graft from the patient with a second surgical site. Because of the increased risk to the patient with autogenous bone grafts, the current standard of care is an allograft, which is a bone graft harvested from cadaver sources such as Freeze-Dried Bone Allograft (FDBA). While allografts can only possess the qualities of osteoinduction and osteoconduction, they also have dramatically less morbidity due to the lack of a second surgical site. Studies have shown that autogenous dentin grafts promote all three ideal mechanisms for bone regeneration. There are two methods to generate autogenous dentin grafts. One is to collect the extracted tooth and to send it to a tooth bank for the preparation process. The second is to process the extracted tooth in a clinical setting chairside, for a graft. A dentin graft can undergo different treatments such as demineralization, mineralization, and partial-demineralization. Although the autogenous dentin graft has shown positive results for bone regeneration, the comparison between partial-demineralized, mineralized autogenous dentin grafts, and freeze-dried bone grafts in the clinical setting for immediate grafting has not been studied in humans. Thus, there is a need to study the benefits of autogenous dentin partial-demineralized and mineralized grafts versus freeze-dried bone allografts regarding clinical, radiographically (bone volume and density), and efficacy results. This research addresses these areas of need.
This study is designed to assess the effects of Alveolar Ridge Preservation (ARP) after tooth extraction compared to extraction alone in the posterior maxilla. The results of this study will demonstrate if the use of ARP reduces alveolar ridge resorption at 6 months post extraction in the posterior maxilla region.
Randomized Controlled study to compare the effectiveness of two different treatment approaches using a new moldable beta-tricalcium phosphate(TCP) bone graft material in ridge preservation of an atraumatic extraction socket site compared to allograft with collagen plug.
GUIDOR Growth Factor Enchanted Bone Graft Substitute (GFeBGS) when used in periodontal surgery will shown greater gum and bone regeneration when compare to bone graft substitute alone. Also, to find the optimal dose.
This randomized clinical trial will involve at least 25 patients who have selected to receive a dental implant to replace a missing tooth. One group will receive the test treatment of a bone graft and a dissolvable membrane at the outer surface of the dental, while the control group will not receive the bone graft and membrane adjacent to the implant. The following will be measured: bone thickness and height adjacent to implant, inflammation of gum tissue, recession of gum tissue, bleeding, pocket depth, and implant success. Patients will be followed for 1 year, including evaluation time points at 2 weeks, 1 month, 3 and 6 months, and 1 year. Statistical analysis of the data will be conducted. The hypothesis is that there is no difference with regard to bone thickness, bone height, pocket depth, bleeding, and implant success rate for grafted implant sites compared to non-grafted implant sites.
This is a prospective, multi-center study to evaluate the use of CopiOs Pericardium Membrane, a bovine xenograft, with use of Puros Cancellous Particulate Allograft, for the augmentation of localized alveolar ridge defects on either the maxilla or mandible.
The hypothesis of this study is that there is a significant difference in bone maturation after sinus grafting determined by the distance from the buccal to the palatal wall of this cavity.
The aim of this case series is to evaluate the outcomes of horizontal ridge augmentation performed using a combination of demineralized freeze-dried bone allograft layered with xenograft bone with a resorbable native collagen membrane.

While allografts can only possess the qualities of osteoinduction and osteoconduction, they also have dramatically less morbidity due to the lack of a second surgical site. Our null hypothesis states that: Experimental groups (mineralized, and partially demineralized dentin grafts) do not show positive changes in implant stability, survival, failure rate, probing pocket depth, and interproximal crestal bone level changes when compared to FDBA Our alternative hypothesis states that: Experimental groups (mineralized, and partially demineralized dentin grafts) show similar or better results in terms of implant stability, survival, failure rate, probing pocket depth, and interproximal crestal bone level changes when compared to FDBA.
To compare dimensional changes in extraction socket of single rooted teeth, 6 months post extraction, when grafted with xenograft versus allograft.
The revised purpose of this study is to compare and evaluate the stability of the implant body, survival rate, bone-level changes, and the implant's soft-tissue outcomes over a period of 1 year. Only 1 tooth is studied per participant. In July of 2024, the revised protocol and revised Statistical Analysis plan were amended post-hoc, and the revised protocol and statistical analysis plan were approved by the IRB review committee in July of 2024. As a result, the study has been terminated due to a change in the study's data analysis, and so the study will only analyze data up to and including the 1-year point.
The purpose of this study is to clinically, radiographically and histologically evaluate the healing sequence of post-extraction sockets grafted with Bio-Oss Collagen® at 3, 6 and 9 months following tooth extraction in single-rooted tooth sites. Subjects with single rooted teeth planned for extraction and replacement with endosseous dental implants will be recruited for the study based on the eligibility criteria and will be divided in three groups (Groups 1, 2 and 3).A cone-beam computed tomography (CBCT) scan will be obtained and reviewed to prepare for the surgical approach and evaluate the ridge dimensions, the tooth planned for extraction as well as the adjacent sites. After tooth extraction, the socket will be grafted with Bio-Oss Collagen® and, depending on the morphology of the extraction sockets, a collagen matrix (Mucograft® seal) and/or a restorable collagen membrane (BioGide®)will be placed to cover and stabilize the graft. Patients will return at 2 and 6 weeks post-extraction to evaluate the healing. A second CBCT will be obtained 2 weeks prior to implant placement to evaluate the ridge dimensions and compare them to the baseline data. Implant placement will take place at 12, 24 and 36 after tooth extraction for Groups 1, 2 and 3 respectively. A bone core biopsy will be obtained at the time of implant placement and will be sent for histological analysis. Patients will return for a post-operative visit at two weeks. Clinical indices (probing depth, recession, bleeding upon probing, keratinized mucosa height, plaque and gingival index), patient reported outcomes and marginal bone levels via standardized periapical radiographs will be evaluated and recorded at baseline (no more than 30 days following delivery of final implant restoration) 1, 2 and 3 years post-loading.
PURPOSE The purpose of this case series is to clinically, radiographically and histologically evaluate the treatment of dehiscence defects in extraction sockets using a minimally-invasive GBR technique that involves the application of a particulate bone allograft and a non-resorbable PTFE membrane. METHODS Subjects with single-rooted teeth indicated for extraction and interested in future implant therapy for tooth replacement will be recruited on the basis of an eligibility criteria. A buccal or lingual dehiscence defect must strongly be suspected or confirmed upon clinical examination in order for the subject to qualify for study inclusion. A cone-beam computer tomography (CBCT) scan of the arch containing the tooth to be extracted will be obtained prior to tooth extraction. Following minimally invasive tooth extraction and debridement, the socket will be evaluated to verify the presence of a dehiscence defect affecting at least 50% of the bony plate height. After creating a soft tissue 'pouch' using tunneling instruments, a non-absorbable dense-PTFE (dPTFE) barrier membrane that will be trimmed to a size and shape that would allow for complete extension over the existing defect will be tucked between the mucosa and the alveolar bone. Then, the extraction socket will be grafted with particulate allograft and the access to the socket will be sealed with an extension of the membrane and an external cross mattress suture. Subjects will be recalled at 1, 2 and 5 weeks to monitor healing and assess the level of discomfort using a visual analog scale at the end of each visit. At the 5-week visit, the membrane will be gently removed and the exposed area will be left to heal by secondary intention. At 20 weeks after tooth extraction a second CBCT will be obtained to radiographically evaluate the site for implant placement. Bone volumetric reconstructions of the alveolar ridge at baseline and at 20 weeks will be made using the CBCT data to assess changes affecting the bone housing. If the site has healed adequately, implant placement will be planned at 24 weeks after tooth extraction. A bone core biopsy will be obtained at the time of implant placement in order to histologically analyze the characteristics of the grafted substrate. Upon implant placement with primary stability a healing abutment will be placed and sutures will be given to achieve primary wound closure, as necessary. Subjects will return for the final study visit at 2 weeks following implant placement to evaluate the healing prior to being referred back to the restorative dentist.
This study will evaluate the effect of allograft bone particle size on the bone quantity and quality following socket grafting and lateral ridge augmentation in preparation for endosseous implant placement. Pre (baseline)- and post-grafting (3 months for sockets and 6 months for edentulous ridges) clinical as well as 2- and 3-dimensional radiographic measurements will be used to evaluate the differences between sites grafted with small vs. large particle sized bone allografts. Histological analysis will be performed at time of surgical re-entry of grafted sites to place the dental implants, and assessed for differences in new bone formation between the 2 types of grafts.
This study aims to examine dimensional alveolar ridge alterations and prevent buccal plate resorption and soft tissue recession following immediate implant placement in extraction sockets in the maxillary esthetic zone using different socket morphology-guided treatment modalities. Expected results of the study are: * To have found the optimal materials and GBR procedures modalities for buccal plate resorption degree reduction; * Soft tissue recession and best esthetic result achievement. There will be possibilities to study socket morphology influence on final esthetic result achievement.
