Effects of Quartz Splint Woven fiber periodontal fixtures on evaluating masticatory efficiency and efficacy

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.
