Background: Immediate occlusal and non-occlusal loading protocols have been discussed and, despite varying success rates, are considered viable in selected cases. Preoperative implant planning and intraoperative transfer are essential to the success of implant-supported reconstructions in partially or completely edentulous jaws.
Purpose: This study was performed to compare clinical outcomes of immediate occlusal versus non-occlusal loading of posterior implants.
Materials And Methods: Of 19 patients with 52 screw-type implants replacing mandibular molars or premolars, nine patients with 21 implants were randomized to a study group that received immediate restorations with occlusal loading, whereas 10 patients with 31 implants were randomized to a control group that received provisional restorations without occlusal loading. Occlusal loading was defined as full loading in maximum intercuspidation. Single-tooth or splinted multiunit restorations were incorporated by screw retention or cementation. Marginal bone defects (MBD), implant survival, and implant success were evaluated 12 months after insertion.
Results: Both groups revealed similar MBD levels consistent with previous reports. No implants were lost (overall survival: 100%) or found to fail (overall success: 100%). No significant intergroup differences were noted for any of the evaluated parameters.
Conclusions: Immediate restorations in partially edentulous mandibles demonstrated successful clinical and radiographic 12-month results. Larger long-term prospective studies are needed to confirm the final evidence and predictability of immediate functional loading as a standard treatment concept for partially edentulous jaws.

Background: Achieving initial implant stability at the molar extraction site can be challenging due to bone width, quality, and anatomical limitations like the maxillary sinus and inferior alveolar nerve. The implant placement should achieve precise centralization with the interradicular septum to facilitate implant stabilization and preservation/regeneration of the alveolar ridge post-extraction with bone grafting. Immediate non-occlusal crown placement aids peri-implant tissue maturation for the desired outcome.

Purposes: To examine differences between immediate and delayed dental implant loading in maxillary aesthetic areas.
Methods: In this retrospective controlled analysis, 43 subjects who underwent immediate placement of the dental implant in a post-extraction socket were ranked into either immediate (24 implants loaded with non-occlusal tooth-like profile provisional prostheses fabricated by virtual diagnostic impressions and an in-office dental milling machine) or delayed group (19 implants loaded with conventional cover screws and secondary intention healing). Intraoperatively and then four months later, scans of the external layers were acquired with an optical scanner.

Objective: To analyze the biomechanical mechanism of mandibular symphyseal fracture combined with bilateral intracapsular condylar fractures using finite element analysis (FEA).
Methods: Maxillofacial CT scans and temporomandibular joint (TMJ) MRI were performed on a young male with normal mandible, no wisdom teeth and no history of TMJ diseases. The three-dimensional finite element model of mandible was established by Mimics and ANSYS based on the CT and MRI data.

Aim: To compare immediate versus early non-occlusal loading of dental implants placed flapless in a 10-year, parallel group, randomized clinical trial.
Materials And Methods: Patients were randomized to receive implants for fixed partial dentures. The immediate group was represented by immediate non-occlusal implant loading, whereas the early group was represented by early non-occlusal implant loading.

Background: Replacement of missing teeth in the anterior aesthetic zone has challenged clinicians with fixed, removable or implant prosthodontics. Problems have been encountered could void aesthetic and functional results. The aim of this study was to present a clinical case report in which clinician challenged a very strong aesthetic case with an innovative surgical and prosthetic approach.
