Evaluation of success of dental implants in immediate vs delayed loading, post radiation in head and neck cancer patients: a systematic review and meta analysis

Background Dental implantology has transformed oral rehabilitation over the past forty years by providing an essential treatment to restore both oral function and aesthetics. The notion of osseointegration has surfaced as a crucial element that substantially contributes to the revolutionary effects of dental implant treatments. Aim The difficulties with oral rehabilitation following ablative surgery for head and neck cancer are examined in this study. To improve treatment outcomes for this patient population, it compares immediate and delayed loading approaches when evaluating the efficacy of dental implants and their survival rates. Methodology 27 pertinent articles that satisfied the inclusion criteria were found after a thorough search of several databases, including PubMed, MEDLINE, Embase, Google Scholar, and the Cochrane Library. Data extraction and a thorough quality assessment of the chosen studies were carried out by 4 independent reviewers. To combine the data and extract significant findings, statistical analysis including meta-analysis was applied. Results The meta-analysis of present study demonstrates a considerable improvement in treatment outcomes when implants are loaded immediately as opposed to delayed. Even then, it is important to recognize that different research designs and participant profiles have different effects on survival of implants. All things considered, the data strongly point to the conclusion that immediate loading produces better outcomes, which may make it the intervention of choice for the outcomes under analysis. Conclusion This analysis emphasizes that HNC patients require customized care, with early loading being preferred for higher success rates and faster recovery. Improved results with immediate loading and individualized overdenture programs have been stated by patients. Further studies that prioritize long-term follow-up and protocols are essential to improving oral rehabilitation for HNC patients.
