Summary
This study found no significant difference in implant or prosthesis failures between 1-stage and 2-stage dental implant procedures. However, the 1-stage approach may be preferable for partially edentulous patients, shortening treatment time.
Area of Science:
- Dental Implantology
- Oral Surgery
- Prosthodontics
Background:
- Dental implants can be placed using a 1-stage (mucosa-penetrating) or 2-stage (submerged) procedure.
- The 2-stage approach minimizes early loading but requires a second surgery and extends healing time.
Purpose of the Study:
- To compare the effectiveness of 1-stage versus 2-stage dental implant placement procedures.
Main Methods:
- Systematic review and meta-analysis of randomized controlled trials (RCTs).
- Searched Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE, EMBASE, and contacted manufacturers.
- Included RCTs with a minimum 6-month follow-up after loading, comparing 1-stage and 2-stage procedures.
Main Results:
- Five RCTs involving 239 patients were analyzed.
- No statistically significant differences were found in prosthesis or implant failures between the two procedures.
- Trends favored the 2-stage approach in fully edentulous patients.
Conclusions:
- The limited number of patients precludes definitive conclusions.
- 1-stage procedures may be advantageous for partially edentulous patients, reducing surgical interventions and treatment duration.
- 2-stage procedures might be indicated for suboptimal primary implant stability, guided tissue regeneration, or when excessive forces are anticipated.
