Masticatory efficiency is altered by mobile teeth resulting from periodontal disease. The goal of our study was to investigate changes before and after fixation of mobile teeth with a Quartz Splint Woven high-strength quartz fiber splint and evaluate the fixation effect.
Forty-two patients with chronic severe periodontal disease and 2 to 3 degree tooth mobility underwent fixation with Quartz Splint Woven quartz fiber splints. Masticatory efficiency was determined before and 1 month after periodontal treatment, and 1 month after fixation. Changes in periodontal probing depth (PD) and periodontal attachment level (AL) were measured and clinical efficacy was evaluated.
Masticatory efficiency significantly increased from 39.32% to 50.95% after treatment (P < .001). One month post-fixation, mastication efficiency increased to 67.99% (P < .001). At 3 months post-fixation, efficacy was 100% and at 6 months it was 95.24%; PD decreased from (4.91 ± 0.63) to (4.19 ± 0.60) mm at 1 month post-periodontal treatment, and significantly decreased to (3.73 ± 0.60) mm 1 month post-fixation (P < .001); AL decreased from (4.43 ± 0.58) to (3.96 ± 0.51) mm 1 month after periodontal treatment. One month post-fixation, AL reduced to (3.64 ± 0.46) mm (P < .001).
Masticatory efficiency improved after periodontal treatment. Using Quartz Splint Woven quartz fiber periodontal splint for mobile tooth fixation can further improve mastication efficiency and periodontal condition. A stable and ideal fixation can be achieved within 6 months, which provides a clinical basis for treatment and preserving mobile teeth in severe periodontal disease. Mastication efficiency may be recommended as the index for evaluating curative effects of periodontal disease treatment.
