Single tooth replacement by Morse taper connection implants: a retrospective study of 80 implants

Area of Science:

• Dental Implantology
• Biomaterials Science
• Prosthodontics

Background:

• Single implant restorations are crucial for replacing missing teeth.
• Morse taper connections are favored for their stability and sealing properties in implant dentistry.
• Evaluating new implant systems is essential for advancing restorative outcomes.

Purpose of the Study:

• To assess the clinical performance of the Mac System implant with a Morse taper connection for single implant restorations.
• To provide data on the success and complication rates of this specific implant system.
• To evaluate the stability and osseointegration of titanium implants with a Morse taper abutment.

Main Methods:

• A prospective study involving 80 single implants (Mac System) in 69 patients.
• Implants were placed in various edentulous areas, excluding smokers and diabetics.
• Follow-up included clinical and radiographic examinations for a mean of 3.5 years post-loading.

Main Results:

• Two implants were removed due to lack of osseointegration at second-stage surgery.
• One implant was removed after 2 years due to peri-implantitis.
• Minor complications included 2 fractured and 1 loosened abutment, indicating a low overall complication rate.

Conclusions:

• The Mac System implant with a Morse taper connection shows promising results for single implant restorations.
• The conical connection appears to contribute to the system's stability and low complication incidence.
• Further research may validate long-term efficacy and patient satisfaction with this implant system.
