Five‐year tomographic and clinical evaluation of the socket shield technique: Case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The socket shield technique, one modality of partial extraction therapy, aims to preserve periodontal tissues and maintain the buccal alveolar bone volume following immediate implant placement or in prosthetic pontic sites, by the strategic maintenance of a tooth root fragment.

Simplified SPAL technique to provide adequate peri‐implant phenotype: A pilot study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Correction of peri‐implant bone dehiscence (PIBD) and optimization of the peri‐implant soft‐tissue phenotype are critical for long‐term peri‐implant tissues stability. A simplified, one‐stage, transmucosal variant of the subperiosteal peri‐implant augmented layer (sSPAL) technique was appraised and evaluated.

Connective tissue graft wall technique for mandibular Class II furcation defects: Two case reports

Clinical Advances in Periodontics, EarlyView.
Abstract Background Furcation involvement (FI) represents one of the most challenging conditions in periodontal therapy due to limited accessibility and the progressive interradicular attachment loss that compromises long‐term tooth stability. Deep periodontal pockets in molars and premolars often present as combined defects, including horizontal FI ...

RESEARCH ON ELASTIC MESHING EFFECT OF RV DRIVE WITH BEVELOID GEAR

Jixie qiangdu, 2020
Finite element contact analysis of a planetary drive with small teeth difference in a beveloid gear RV drive was carried out. The results show that the meshing performance differs from that of the traditional gear design theory result.

Bimanual instrument suturing technique for periodontal and implant microsurgery: A technical note

Clinical Advances in Periodontics, EarlyView.
Abstract Background In the traditional suturing technique, the dominant hand (DH) holds a needle holder, and the non‐dominant hand (NH) performs manual ties without the aid of an instrument. In periodontal and implant microsurgery, finer sutures and needles, e.g., 7‐0 in International Organization for Standardization units, are used, which could be ...

A case series of necrotizing periodontal diseases in hospitalized patients: What hasn't been said yet?

Clinical Advances in Periodontics, EarlyView.
Abstract Background Necrotizing periodontal diseases (NPDs) are uncommon and severe inflammatory conditions characterized by tissue necrosis, painful ulceration, and rapid clinical progression, frequently associated with systemic immunosuppression. Limited data exist regarding their clinical presentation and management in hospital settings.

Tooth contact analysis of mismatched hypoid gears

, 1996
A method for the tooth contact analysis in mismatched hypoid gears is presented. The point contact of mismatched hypoid gears changes into line contact under load and these potential contact lines are determined.
