Summary
Dental implants placed after a graftless maxillary sinus lift show a high survival rate of 97%. This procedure, while effective, requires further research to define optimal indications for graftless sinus augmentation.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Regenerative Dentistry
Background:
- Maxillary sinus augmentation is crucial for dental implant placement in the posterior maxilla.
- Graftless techniques offer an alternative to traditional bone grafting procedures.
- The lateral window approach is a common method for sinus floor elevation.
Purpose of the Study:
- To determine the survival rate of dental implants placed in the posterior maxilla following a graftless maxillary sinus lift.
- To identify factors influencing the success of this procedure.
Main Methods:
- A systematic literature review was conducted across major databases (MEDLINE, EMBASE, LILACS, Scopus, Science Direct) up to June 2016.
- Included studies were in English, Spanish, Portuguese, or French.
- Methodological quality was assessed using the Effective Public Health Practice Project's Quality Assessment Tool.
Main Results:
- Eleven studies (9 prospective, 2 retrospective) met the inclusion criteria.
- All studies involved graftless maxillary sinus lift with immediate implant placement.
- The mean implant survival rate was 97%, with an average intrasinus bone formation of 6.2 mm.
- Included studies exhibited low methodological quality.
Conclusions:
- Graftless maxillary sinus lift via the lateral window approach demonstrates a high dental implant survival rate.
- Further research is needed to establish clear indications and contraindications for this technique.
