Article Abstract
Aim: To assess buccal vertical bone resorption following implant placement in healed sites with varying buccal bone wall thicknesses.
Materials And Methods: In 11 miniature pigs, three tapered hybrid titanium implants were placed per hemi-maxilla in healed bone. Sites were randomised into three groups based on buccal bone wall thickness: G1 (< 1.0 mm), G2 (1.0-1.5 mm) and G3 (> 1.5 mm). Animals were euthanised at 24 h and 2, 4 or 8 weeks. Histological and histometric analyses were performed. The primary outcome was the vertical distance from the transition point (TP) between the machined and moderately rough implant surfaces to the first bone-to-implant contact (fBIC).
Results: Healing was uneventful. At 2 weeks, all groups showed buccal resorption, although G3 exhibited earlier bone apposition and fewer resorptive signs. By 8 weeks, all G1 implants displayed exposure of the moderately rough surface, while only one implant in G3 showed exposure. TP-fBIC values at 8 weeks were 0.92 ± 0.63 mm (G1), 0.27 ± 0.54 mm (G2, p = 0.041) and -0.16 ± 0.17 mm (G3, p = 0.0002). Bone-to-implant contact increased over time across all groups.
Conclusion: Thin buccal bone walls (< 1 mm) were associated with greater vertical bone loss and implant surface exposure, whereas thick walls (> 1.5 mm) preserved the buccal bone better and protected the implant surface.

Objectives: Precise implant placement in the anterior and posterior maxilla often presents challenges due to variable bone and soft tissue anatomy. Many clinicians elect a freehand surgical approach because conventional surgical guides may not always be easy to design, fabricate, or utilize. Guided surgery has been proven to have advantages over freehand surgical protocols and therefore, the present study proposed utilizing the nasopalatine canal (NPC) as an anatomical reference and point of fixation for a novel rotational path surgical template during computer-aided implant surgery (CAIS).

This study aimed to characterize gingival thickness (GT) and determine correlations with other local phenotypic features. CBCT scans from adult subjects involving the maxillary anterior teeth were obtained to assess buccal GT at different apicocoronal levels, periodontal supracrestal tissue height (STH), the distance (CEJ-BC) from the cementoenamel junction (CEJ) to the alveolar bone crest (BC), and buccolingual tooth dimensions. A total of 100 subjects and 600 maxillary anterior teeth comprised the study sample.

Objectives: To assess the stability of hard tissue following simultaneous guided bone regeneration (GBR) in the anterior maxilla, analyze the impact of the buccal bone arch contour on postoperative bone remodeling and restorative outcomes.
Methods: Patients who underwent anterior maxillary implantation and simultaneous GBR were included. Radiographic metrics were evaluated using preoperative, immediate postoperative, and follow-up cone beam computer tomography (CBCT) scans, and esthetic indicators were extracted from follow-up clinical records.
Purpose: This scoping review describes the current evidence on immediate implant placement (IIP) and immediate restoration (IR) in single-unit and multiple-unit fixed dental prostheses regarding anatomical, surgical, and prosthetic factors.
Materials And Methods: Electronic searches were conducted in PubMed, Embase, and Cochrane databases for systematic reviews on IIP and IR in the anterior and posterior regions of the jaws. Bibliometric data and study details were extracted.

Objectives: This study aims to evaluate the short- to medium-term clinical efficacy of demineralized dentin matrix (DDM) particles applied during the immediate implantation of alveolar bone defects in the posterior region.
Methods: A total of 76 patients with 110 simple taper retentive implants were included in the conducted study and divided into Groups A and B in accordance with the bone grafting materials. Cone beam computed tomography and panoramic radiographs were taken immediately after implant surgery, immediate crown repair, and final follow-up time.
