The Influence of Preoperative Antibiotics on Success of Endosseous Implants at 36 Months

Abstract

The benefits of prophylactic antibiotics are well recognized in dentistry. However, their routine use in the placement of endosseous dental implants remains controversial. As part of the comprehensive Dental Implant Clinical Research Group (DICRG) clinical implant study, the preoperative or postoperative use of antibiotics, the type used, and the duration of coverage were left to the discretion of the surgeon. These data for 2,973 implants were recorded and correlated with failure of osseointegration during healing (Stage 1), at surgical uncovering (Stage 2), before loading the prosthesis (Stage 3), and from prosthesis loading to 36 months (Stage 4). The results showed a significantly higher survival rate at each stage of treatment in patients who had received preoperative antibiotics.

Current Trend of Antimicrobial Prescription for Oral Implant Surgery Among Dentists in India

“…Published literature in this context related to either use of AMAs by dental practitioners in routine clinical practice or the success and failure of oral implants with or without AMAs [23][24][25][26][27][28][29][30]. Only one study from Jordan had specifically reported the use of AMAs by dentists performing oral implant surgery [31].…”

An investigation of antibiotic prophylaxis in implant practice in the UK

“…19,20 The research to date with regard to efficacy of antimicrobial prophylaxis in reducing failure of integration of implants and reducing postoperative complications remains equivocal. 8,21,22 The General Dental Council (GDC) has stated that 'a UK-qualified dentist would not be expected to be competent to practise implant dentistry without undertaking • Suggests that there is currently a wide variation in prescribing patterns for antibiotic prophylaxis when placing dental implants.…”

Concept of Healing After Dental Implant Placement

“…It can be separated into the inflammatory phase, the proliferative phase, and the maturation phase. [4] Phase One: Inflammatory Phase…”

“…Even with the most careful surgical manipulation of osseous tissues, the generation of a thin layer of necrotic bone in the periimplant region is inevitable. [4] In addition, exact microscopic fit between the implant and the surgical defect is not possible, leaving local areas of dead space where the implant does not directly contact osseous tissue.…”
