NCT07512011
This study investigates the outcomes of a surgical procedure that is performed to increase bone support at a future implant site on the upper back jaw area. This procedure requires placing bone graft material and/or substitutes into the maxillary sinus. The average healing time for the graft is about 6 months. Then, the site will be ready for dental implant. The study will compare healing outcomes of two types of bone graft mixtures used on the same patient (right and left upper jaw regions). The outcomes will be evaluated through clinical examination but also by studying the quality of the tissue through tissue biopsies obtained from grafted sites.
NCT07460648
Modified socket shield therapy (SST) has been proposed to preserve the facial plate and peri implant tissues. Whether spontaneous healing after two stage modified SST provides outcomes comparable to grafted SST before delayed implant placement remains unclear.
NCT07296302
Tooth extraction sites often require alveolar bone grafting to preserve ridge dimensions and improve conditions for future implant placement. Although systemic antibiotic prophylaxis is commonly prescribed after grafting procedures, there is limited evidence supporting its necessity in healthy patients undergoing intraoral bone grafting. This randomized, double-blind, placebo-controlled clinical trial aims to compare the effects of prophylactic amoxicillin versus placebo on postoperative outcomes in alveolar bone graft procedures using Plenum® Oss HP biomaterial, a synthetic biphasic bioceramic composed of hydroxyapatite and beta-tricalcium phosphate (HA/β-TCP; 70:30 ratio). Participants will be randomly assigned to receive either amoxicillin 500 mg every 8 hours for 7 days or a matching placebo. Clinical parameters, postoperative complications, and patient-reported outcomes will be assessed. The study seeks to determine whether antibiotic prophylaxis provides measurable clinical benefits or whether placebo yields comparable results, contributing to more rational antibiotic use and supporting antimicrobial stewardship in oral surgery.
NCT07295041
This study aimed to compare two different methods used to augment bone in the posterior lower jaw prior to implant placement in patients with insufficient bone width. Eligible patients were included in the study and received a horizontal bone augmentation with one of two methods, which differed in the materials used for the bone augmentation. The group allocation was randomised. After 6 months of healing following parameters were assessed: histological evaluation, survival of the bone graft, the need for further bone augmentation at the time of implant placement, changes in soft tissue characteristics, radiologically and clinically assessed changes in bone width.
NCT06624982
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.
NCT07153185
The goal of this retrospective PMCF study is to assess safety and performance of creos xenoprotect in all indications functioning as dental barrier membrane. The primary endpoint of the study is the occurrence of major complications during 6 months after creos xenoprotect placement whereas the hypothesis is that these major complications occur in less than 5% within this timeframe. This is a retrospective, multicenter clinical investigation with consecutive cases. Data will be collected on consecutive data cases from patient files, given that these patients were treated within a defined indication with creos xenoprotect in the past. Patients participating in this study do not have any obligations or need to come back for any intervention. A total of 11 centers are planned to be included. Sample size is n=200 patients and is distributed equally in four indication groups: Group 1: Ridge augmentation (vertical and horizontal) Group 2: Alveolar ridge preservation Group 3: Sinus floor augmentation Group 4: Augmentation around implant or teeth
NCT05972876
Rationale Graft maturity is correlated with strength and biomechanical properties of the reconstructed ACL. There are concerns that heavy-load resistance training (HLRT) may have detrimental effects on ACL graft maturation. Therefore, low-load blood flow restriction training (LL-BFRT) has been suggested as an alternative to HLRT. As LL-BFRT is an increasingly popular method for the rehabilitation after an ACL reconstruction, it is important to evaluate the value of this treatment. Objectives The main objective is to evaluate the effect of LL-BFRT on MRI-based graft maturity after ACL reconstruction compared to HLRT. The secondary objectives are the effect of LL-BFRT on donor-site morbidity, range of motion, knee stability, patient reported outcome measurements, muscle strength, safe return to pre-injury level of sport and patient satisfaction. Furthermore, feasibility and safety of rehabilitation will be assessed. Study design Randomized controlled trial . Study population Patients who will undergo primary bone-patellar tendon-bone ACL reconstruction and rehabilitation at Knie-Heup centrum Plus will be assessed for eligibility. The exclusion criteria are: venous thromboembolism, sickle cell anemia, severe hypertension, contra-indication for accelerated rehabilitation, contra-indication for MRI scan or patients who are not willing/able to participate. Intervention LL-BFRT includes 12 weeks of biweekly strength training and starts two weeks after surgery. Comparison HLRT includes 12 weeks of biweekly strength training and starts two weeks after surgery. Main study endpoints The main endpoints are MRI-based graft maturity defined as signal-to-noise quotient three and nine months after surgery.
NCT06795919
In the past few years, periosteal membrane has been used in orthopedic surgery as well as periodontal surgery as a mechanism to promote bone healing without the ingrowth of fibrous tissues. It has shown its efficiency in maintaining the bone volume and density in postoperative follow up. This can in turn solve the problem of potential bone loss in patients of alveolar cleft. The study aims to see if fixing the periosteum of the anterior ilium with tacks after bone graft application in the donor site will help maintain the graft and promote healing for the alveolar cleft patients
NCT06727591
The aim of this study was to compare clinically and radiographically bone gain, healing of the surgical site, healing of the grafted bone and stability of the grafted area following horizontal ridge augmentation at anterior mandible using split bone block from the chin area.
NCT06627621
This study aimed to evaluate the effectiveness of synthetic polycaprolactone (PCL) bioscaffold membranes used for alveolar augmentation in maxillofacial surgery for increasing the amount of newly formed bone after three-dimensional application.
NCT06541236
According to the scientific literature, the loss of any tooth can be accompanied by a pronounced resorption of the alveolar ridge in the corresponding area, which leads to the formation of various defects. In the post-extraction period, bone tissue resorption 4 months after tooth extraction is up to 45% horizontally and 43% vertically.Despite the considerable amount of research on this problem, the improvement of pre-implantation preparation of patients with adentia after tooth extraction continues to be an extremely urgent task. The solution to this problem requires a comprehensive approach based on a unified assessment of the success of dental implantation in the post-extraction zone. The aim of our study is to conduct a comprehensive comparative analysis of osteoplastic materials after preservation of the extraction wells of extracted teeth. The null hypothesis is that the ADM technique can be used in patients and the newly formed bone regenerate will be sufficient for implant placement.

long-term safety and performance of Ivory Dentin Graft. Ivory Dentin Graft is at least as good as the competitor treatment group (OsteoBiol Gen-Os) for alveolar ridge preservation following tooth extraction.
NCT02526563
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.
NCT03549039
This study included patients who underwent secondary alveolar bone grafting by harvesting graft from the anterior iliac crest, in Oral and Maxillofacial Department, Faculty of Dentistry, Ankara University, Turkey, during the period from January 2012 to March 2016. All patients were operated using the same technique and by the same surgical team. Patients will be interviewed to fill Short-Form Health Survey (SF-12) and Postsurgical Patient Satisfaction Questionnaire (PSPSQ) 6 months postoperatively. The questionnaires will be used to assess the relationship between health quality and patient satisfaction. Also, grafted sites will be evaluated with respect to fistula, the presence of cleft palate, and infection.The descriptive statistics and Pearson correlation analyses will be made using PSPSQ scores and SF-12 PCS and MCS scores.
NCT02406924
Twenty four patients with bone resorption on the anterior maxilla will be divided into two groups with different kinds of grafting: bone block associated with particulated biomaterial and particulated mixture of autogenous bone and biomaterial stabilized by collagen membrane and pins. The techniques will be compared according to volume gain, quality of graft osseointegration, implant survival and maintenance of the level of soft tissues.
