Loading protocols in dental implantology: A narrative review

ABSTRACT Introduction: Dental implant success depends significantly on loading protocols, with immediate loading gaining popularity due to patient demands for faster, esthetic results. While conventional and early loading offer predictable outcomes, immediate loading carries higher failure risks, especially in compromised cases. Progressive loading offers a balanced alternative by gradually increasing implant load. This review aims to review and analyze various dental implant loading protocols, with a focus on their effects on osseointegration, implant stability, and long-term success. Methods: Relevant research articles published between January 1960 and December 2024 were identified through comprehensive searches of electronic databases, including EBSCO, EMBASE, PubMed, Web of Science, and the Cochrane Library, with terms such as “Conventional Loading, Delayed Loading, Dental Implants, Immediate Loading, and Progressive loading” were collected. Results: Based on the inclusion and exclusion criteria, 11 studies were selected for this review. Both conventional and early loading protocols demonstrate well-established predictability and consistently high success rates. In contrast, immediate loading, though beneficial in terms of reduced treatment time and patient satisfaction, demonstrates variable outcomes, particularly in partially edentulous cases and compromised sites. Progressive loading emerges as a viable alternative, gradually increasing functional demands on the implant to enhance stability while mitigating failure risks. Discussion: The primary limitation identified is the relative paucity of robust, long-term evidence supporting immediate loading in all clinical scenarios. Clinicians must weigh the risks of early implant failure against the benefits of faster treatment in select patient groups. The article concludes that while immediate loading has a place in modern implantology, its application should be carefully considered, particularly in patients with risk factors for impaired healing.
