None:
Edentulism causes aesthetic, functional, nutritional, phonetic and psychological damage. One of the best treatments for it is implant-supported full-arch prostheses. However, like all techniques, it involves challenges.
Aim:
To evaluate the main complications in implant-supported complete dentures.
Materials And Method:
This study analyzed the medical records of 140 patients rehabilitated with implant-supported full-arch prostheses with immediate loading using the passive fit technique. The analysis considered the antagonist, and complication location (upper and/or lower jaw). All cases had 1 to 8 years under load.
Results:
No complication was reported in 115 (82.1%) patients, while 25 presented complications: 14 (56%) prosthetic tooth fractures, 3 (12%) prosthesis retention screw fractures, 3 (12%) loss of cementation of the cylinder, and 5 (20%) implant losses. There were more complications in implant-supported complete dentures in the upper arch or cases of both jaws (p<0.05). The success rate (patients without complications during follow-up) was 82.1%.
Conclusion:
Implant supported complete dentures made by the passive fit technique were predictable in the long term for rehabilitation of completely edentulous patients.
