Summary
Early-loaded Defcon implants show high survival rates, comparable to literature data for conventional loading. This study confirms the efficacy of early loading protocols for dental implants.
Area of Science:
- Dentistry
- Oral Implantology
- Prosthodontics
Background:
- Early loading protocols for dental implants are increasingly utilized.
- Assessing implant survival rates is crucial for clinical decision-making.
Purpose of the Study:
- To estimate the 1-year survival rate of early-loaded Defcon treatment surface Avantblast (TSA) implants.
- To compare the success rate of these implants with literature data for conventionally loaded implants.
Main Methods:
- Retrospective case series of 642 Defcon TSA implants placed and early-loaded between 2002 and 2005.
- Implant success defined by Buser's clinical and radiologic criteria with a 1-year follow-up.
- Analysis included patient demographics, implant parameters, and prosthetic data.
Main Results:
- A total of 642 implants were placed in 192 patients, rehabilitated with 298 prostheses.
- The 1-year implant survival rate was 98.13%.
- Literature review indicated a 98.4% success rate for early loading between 2001 and 2005.
Conclusions:
- The observed success rate of early-loaded Defcon TSA implants is comparable to published data.
- Early implant loading demonstrates a high success rate, supporting its clinical application.
