Surgical Guide Versus Freehand Dental Implants Placement

This randomized clinical trial compares the accuracy of dental implant placement performed using a surgical guide with that achieved using the conventional freehand technique. Participants requiring dental implant placement are allocated to either guided implant placement or freehand implant placement. The postoperative position of the implants is compared with the virtually planned implant position using three-dimensional image superimposition. The primary objective is to determine whether the use of a surgical guide improves the positional accuracy of dental implant placement compared with the freehand approach.

Effect of Advanced PRF and Hyaluronic Acid on Dental Implant Healing

This randomized parallel-group clinical trial aimed to evaluate the clinical efficacy of advanced platelet-rich fibrin (A-PRF) combined with hyaluronic acid (HA) in enhancing peri-implant bone formation in patients undergoing delayed dental implant placement. Participants will be allocated to either a test group, in which A-PRF combined with HA is applied at the implant site, or a control group receiving conventional implant placement without adjunctive biomaterials. Peri-implant bone changes will be assessed using cone-beam computed tomography (CBCT), including radiographic bone density and bone volume measurements. Implant stability will also be evaluated using resonance frequency analysis at the time of implant placement and during follow-up. Additional clinical outcomes include postoperative pain and implant survival. The participants will be followed up for six months after implant placement.

Ozone Versus Conventional Socket Disinfection for Primary Dental Implant Stability

This randomized split-mouth controlled clinical trial aims to compare the effects of ozone and conventional implant site disinfection on primary and early secondary implant stability. Systemically healthy adults requiring at least two dental implants in symmetrical or contralateral edentulous sites will receive ozone disinfection at one implant site and conventional disinfection at the paired site according to a randomized allocation. Implant stability will be assessed immediately after implant placement using insertion torque and resonance frequency analysis (Implant Stability Quotient, ISQ), and secondary stability will be evaluated by ISQ measurements at the 3-month follow-up during healing abutment placement. The study will determine whether ozone disinfection improves implant stability during the early osseointegration period.

Implant Placement Depth and Peri-Implant Tissue Outcomes

The primary aim of this randomized clinical trial is to evaluate the influence of subcrestal implant placement depth (-2 mm vs -4 mm) on peri-implant marginal bone level changes, including marginal bone loss and bone remodeling. Secondary outcomes include implant success, peri-implant probing depth (PPD), and bleeding on probing (BoP). Partially edentulous patients requiring fixed implant-supported prosthetic rehabilitation with two implants in posterior maxillary or mandibular regions will be included. Implants will be placed subcrestally at either -2 mm or -4 mm from the bone crest, following a submerged healing protocol. Allocation to insertion depth will be randomized. Marginal bone level changes will be assessed using standardized periapical radiographs at second-stage surgery, prosthesis placement, and at 1, 3, 6, and 12 months after functional loading. PPD and BoP will be recorded at the same time points.

Clinical and Radiographic Evaluation of Delayed Dental Implant Placement After Socket Preservation Using Injectable Bone Graft

This clinical study aims to evaluate the clinical and radiographic outcomes of delayed dental implant placement following socket preservation using an injectable alloplastic bone graft material. The study will include patients who require tooth extraction and are candidates for implant placement. After tooth extraction, the socket will be preserved using the bone graft material, and dental implants will be placed after a healing period. Clinical and radiographic assessments will be performed to evaluate bone quality, bone height, and implant stability. The goal of this study is to determine the effectiveness of injectable alloplastic bone grafts in maintaining the alveolar ridge and improving the success of delayed implant placement.
