Clinical effects of movable dentures versus fixed dentures in repair for patients with periodontal disease and dental defect
Objective To compare the clinical effects of movable dentures and fixed dentures in the treatment of patients with periodontal disease and dentition defect.Methods Ninety patients with periodontal disease and dentition defect treated at Department of Stomatology,Nanyang Central Hospital from March 2022 to February 2024 were selected for the randomized controlled trial,and were divided into a reference group and an experimental group by the random number table method,with 45 cases in each group.There were 22 males and 23 females in the reference group;they were(46.52±8.14)years old;their disease course was(3.06±1.05)years.There were 24 males and 21 females in the experimental group;they were(46.81±8.33)years old;their disease course was(3.11±1.12)years.The reference group were treated with movable dentures,while the experimental group with fixed dentures.The masticatory function,temporomandibular function,oral function before and after the treatment and therapeutic effects were compared between the two groups.t and x2 tests were applied.Results Before the treatment,there were no statistical differences in the masticatory function,temporomandibular function,and oral function between the two groups(all P＞0.05).After the treatment,the maximum occlusal contact area,bite force,and masticatory efficiency in the reference group were higher than those in the experimental group[(231.05±21.52)mm2 vs.(205.49±20.03)mm2,(140.05±14.32)lbs vs.(131.01±13.92)Ibs,and(86.72±7.23)％vs.(80.80±6.81)％];the asymmetry index of bite force and scores of clinical dysfunction index,temporamandibular joint disturbance index,oral pain,oral health,tooth mobility,and gingival bleeding in the experimental group were lower than those in the control group[(14.05±1.32)％vs.(20.01±2.92)％,(4.21±1.06)vs.(5.85±1.56),(0.08±0.02)vs.(0.14±0.03),(3.66±1.01)vs.(4.31±1.16),(16.08±1.72)vs.(22.72±2.23),(4.48±1.02)vs.(7.31±1.71),and(1.16±0.51)vs.(1.81±0.66)];there were statistical differences(t=5.832,3.036,3.998,12.476,5.833,7.442,2.834,15.816,9.534,and 5.227;all P＜0.05).The effective rate of the experimental group was higher than that of the control group[95.56％(43/45)vs.77.78％(35/45)],with a statistical difference(x2=6.153;P=0.013).Conclusions In the treatment of patients with periodontal disease and dentition defect,fixed dentures can more effectively restore their chewing function,provide more balanced force distribution,and help reduce periodontal tissue damage.Moreover,fixed dentures are more effective in improving symptoms of temporomandibular joint disorders,oral comfort,overall health status,and clinical treatment effect,so it is worth being generalized.
