Objective: The objective of the study is to compare two different implant designs having different neck configuration and neck interfaces.
Materials And Methods: Fifty subjects were randomly divided into 2 groups, each containing 25 subjects. In Group I, conical connection (CC) (Nobel Biocare) with back-tapered collar dental implant and in Group II, external-hexagon (EH) (Nobel Biocare) with flat-to-flat implant-abutment interface dental implant was used. Radiographic marginal bone crest level and marginal bone loss (MBL) were compared.
Results: A significant less MBL was seen in Group I compared to Group II recorded at different intervals of time ( < 0.05).
Conclusion: CC implants with back-tapered collar exhibited less MBL as compared to EH implants with flat-to-flat implant-abutment interface.

Real-time surgical navigation systems (dynamic computer-aided surgery, d-CAIS) and static guided surgery (static computer-aided surgery, s-CAIS) have been shown to enhance the accuracy of zygomatic implant (ZI) placement. The objective of this systematic review was to evaluate and compare the accuracy and risk of complications associated with d-CAIS and s-CAIS in ZI placement. A systematic review of published studies involving more than 4 patients was conducted to assess and compare the accuracy of d-CAIS and s-CAIS in zygomatic implant placement.

The long-term success of dental implants depends on the ability of soft tissues to form a protective barrier, limiting pathogen infiltration into peri-implant tissues. Here, we investigated the impact of an anodized surface modification on mucosal integration. Scanning electron microscopy and surface chemistry characterization were carried out on miniaturized implants.

Objectives: Primary stability (PS) is a key factor for promoting osseointegration and long-term success of dental implants particularly for immediate loading protocols. Beyond the current assessments of PS, an accurate pre-operative evaluation of PS would contribute to the improvement of surgical planning and treatment outcome. This study used biomechanical testing and homogenized finite element (hFE) analysis to objectively measure PS in the laboratory, and digitally estimate PS from prior μCT reconstructions.

Article Synopsis
- * RS demonstrated the most precise implant positioning with the least deviation, while SG proved to be faster and led to better recovery in the short term.
- * All methods resulted in similar soft tissue healing and patient satisfaction, but each method also presented unique advantages and cost considerations.

Objective: Assess whether horizontal ridge augmentation with guided bone regeneration (GBR) using deproteinized bovine bone mineral (DBBM), autologous bone, and a resorbable collagen membrane supports successful implant placement.
Materials And Methods: This open, prospective, single-cohort, multicenter clinical study included patients with ridge defects that required GBR prior to implant insertion. The primary endpoint was radiologically assessed bone gain after 8 months post-GBR, measured at the center of planned implant sites.
