Comparison of Bone Healing in Immediate Implant Placement versus Delayed Implant Placement

With increasing experience and in an attempt to shorten overall treatment times, implant placement in combination with tooth extractions and sinus lift procedures has become popular. In both cases, primary stability has to be achieved by either engaging apical and oral regions of trabecular bone or by engaging residual host bone beneath the sinus cavity. Extraction sites were formed by pressing a root analog into homogeneous low density polyurethane foam which was used as bone surrogate while a 3 mm thick sheet of medium density foam was used for mimicking a sinus lift situation. Two types (n = 10) of bone level implants with a conventional tapered design and a cervical back taper (NobelActive; control) and a novel design characterized by a shift in core diameter and thread geometry (AlfaGate; test) were placed in these models following conventional osteotomy preparation. Insertion torque was measured using a surgical motor and primary stability was determined by resonance frequency analysis. Statistical analysis was based on Welch two sample t tests with the level of significance set at α = 0.05. In sinuslifting, NobelActive implants required significantly higher insertion torques as compared to AlfaGate (p = 0.000) but did not achieve greater implant stability (p = 0.076). In extraction sites, AlfaGate implants showed both, significantly higher insertion torques (p = 0.004) and significantly greater implant stability (p = 0.000). The novel implant design allowed for greater primary stability when being placed in simulated extraction sockets and sinuslift situations. While in extraction sockets the position of condensing threads in combination with an increase in core diameter is beneficial, the deep cervical threads of the novel implant lead to superior performance in sinuslift situations.

BackgroundA dental implant is used in the treatment of complete and partial edentulism. Implant application has increased significantly in modern dentistry. The anatomy, medical condition, practitioner knowledge, and surgical technique are key factors that eventually affect the overall outcome of dental implants. For a better treatment outcome for dental implants, adequate multidisciplinary communication, cooperation, and support must be achieved while considering the periodontics, prosthodontics, and oral surgery specialties. ObjectiveThis study aims to compare the knowledge and skills regarding up-to-date implant techniques among prosthodontists, periodontists, and oral surgeons in Riyadh, Saudi Arabia. Materials and methodsThe data were collected from prosthodontists, periodontists, and oral surgeons working in Riyadh, Saudi Arabia from April 2022 to August 2022. The targeted subjects were residents, specialists, and consultants working in Riyadh, Saudi Arabia. ResultsA total of 181 dentists were surveyed in the current study. A significantly higher proportion of oral surgeons have perceived that the BTI brand (BTI Biotechnology Institute, Álava, Spain) had a high load torque before screw fracture (p = 0.025). Periodontists had significantly higher knowledge levels related to the technique with the lowest marginal bone loss (p = 0.003). Knowledge levels were significantly higher among prosthodontists for the items related to the fact that both early and late implant placement following alveolar ridge placement would have the least changes in periodontal parameters (p = 0.013). ConclusionAll the targeted specialties exhibited a comparable impression regarding implant techniques and their outcomes. Each specialty had its own aspect of treatment during the placement of dental implants depending on multiple factors. Significant knowledge was observed from each specialty regarding implant brands, techniques, and antibiotic prescriptions for dental implants.
