A comparative study of deformation in hexagonal and star-shaped implant screwdriver heads

BMC Oral Health
Background Dental implants are a popular and effective solution for replacing missing teeth. However, there are challenges such as screw loosening and component failure. This deformation can impact torque application and screw retention.

Papilla‐Preserving Gingival Fiber Retention Osseous Surgery in the Anterior Maxilla: A Novel Clinical Technique

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To describe papilla‐preserving gingival fiber retention osseous surgery (PP‐FibReOS), a biologically driven resective approach intended to eliminate periodontal pockets while maintaining interproximal connective tissue and papillary stability in esthetically demanding maxillary anterior sites.

Analysis of optimizing Bicon short implant placement in posterior mandible with type II bone

BMC Oral Health
Background Dental implantation has emerged as the predominant approach for the replacement of missing teeth. Nevertheless, the resorption of alveolar bone occurs progressively following tooth loss, leading to varying perspectives regarding the ...

Long‐Term Survival Rates of Dental Implants in Patients With Disabilities: A Retrospective Clinical Study With up to 10 Years Follow‐Up

Journal of Oral Rehabilitation, EarlyView.
Dental implants in patients with disabilities show high 10‐year survival (98.3%) when supported by principled screening and structured maintenance. This study reveals that while biological failure is rare post‐loading, frequent mechanical complications—predominantly decementation—remain a significant clinical challenge requiring vigilant long‐term ...

Comparison of stress distribution around splinted and nonsplinted implants with different crown height space in posterior mandible: A finite element analysis study

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this finite element analysis (FEA) study was to analyze the stress distribution on prosthetic components of splinted and nonsplinted prostheses, bone, and implants with different crown height space (CHS). Materials and Methods Mandibular posterior segment was modeled with no resorption at the second premolar site and ...

Effect of build orientation on the fabrication trueness of additively manufactured implant‐supported complete arch interim fixed prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how build orientation affects the fabrication trueness of additively manufactured implant‐supported complete arch prostheses by comparing them to subtractively manufactured high‐impact polymer‐based prostheses. Materials and Methods An edentulous maxillary model with four implants at canine and first molar regions ...

The effects of anodization and instrumentation on titanium abutment surface characteristics and biofilm formation

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the impact of anodization and instrumentation on titanium abutment surface characteristics (surface roughness and wettability) and biofilm formation (viability and mass). Materials and Methods Titanium discs were obtained from pre‐milled abutment blanks made of titanium‐6aluminum‐7niobium alloy.

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
