Abstract
Objectives
Dental implant therapy has been widely performed in clinical setting to improve esthetics and mastication disorders due to tooth loss by embedding such artificial materials as titanium and BioCelum into the jawbone. Recently, orthodontic specialists make the anchor a fixed source that teeth are moved. The presenters therefore clinically investigated implant-induced maxillary sinusitis because the number of dental treatment is increasing.
Methods
Subjects were 42 patients with 43 cases of maxillary sinusitis caused by a dental implant between 1973 and 2007.
Results
1) Gender and age: The 42 patients comprised 16 men and 26 women. Mean age was 52.6 years. 2) Cause: Dental implant: 42, Anchor treatment by orthodontist: 1. 3) Duration from implant surgery to onset of maxillary sinusitis: Mean duration was 36.3 months (range, 1 month to 12years). 4) Treatment methods: Therapy comprised implant removal, Caldwell-Luc procedure and fistula closure in 20 cases, implant removal and fistula closure in 10 cases, implant or anchor removal and conservative therapy in 11 cases, and conservative therapy alone in 2 cases.
Conclusions
1) In the treatment of maxillary sinusitis caused by a dental implant, the basic strategy was based on the Caldwell-Luc procedure. 2) It is thought that the generation of maxillary sinusitis by the anchor treatment increases in the future. 3) For prevention, thorough anatomical and morphological examinations of the maxilla and proper selection of materials and procedures matching each patient are important.
