Horizontal and vertical rigidity of teeth fixed with seven types of dental splints were evaluated by two tooth mobility measuring devices. Altogether 21 dissected sheep mandibles including soft tissues were used for the experiments in which Fermit, flexible wire-composite, Kevlar, Fiber, Protemp, rigid wire-composite and Triad Gel splints were applied to four incisors. The mean rigidity of the central incisors within the splint was measured by means of Mühlemann periodontometer (horizontal mobility) and Periotest (horizontal and vertical mobilities). Mobility values of teeth before splinting were used as covariants and the values with the splints were illustrated as adjusted mobility. Statistical significance between the rigidity of various splints was analyzed by an unpaired t-test. It was shown that the most rigid splints both in horizontal and vertical directions were Triad Gel, rigid wire-composite and Fermit splints. Kevlar and Fiber splint allowed more horizontal movement than other splints. Protemp and flexible wire-composite splints proved to produce adequate lateral support for the fixed teeth and allowed vertical flexibility which is experimentally known to improve periodontal healing of luxated teeth.
The newer glass/cermet cements possess improved physical properties compared with the original glass-ionomers. The author proposes taking advantage of these improved properties, in a novel use for cermets, in the temporary splinting of traumatized teeth.
AIM: The deep periodontal disease often leads to dental mobility with further aggravation of the symptomatology. The aim of the paper is to verify the importance of splinting of teeth in the therapy of periodontitis on the basis of parameters commonly studied [probing depth (PD), bleeding on probing (BOP), plaque index], and the role of the occlusal trauma as primary factor or second leading factor in periodontal diseases. METHODS: Thirty patients suffering from periodontitis have been treated with the splinting of teeth, neither preceded nor followed from topical and systemic pharmacological therapy, nor from surgical or non surgical treatment of the periodontal tissues involved. During the 4 visits provided by the study, T0 (0 days), T1 (30 days), T2 (90 days) and T3 (180 days), PD, BOP and plaque index have been estimated. RESULTS: From the comparison of the T0 PD and BOP with the T3 PD and BOP, a significant improvement of these parameters is observed (P<0.05). CONCLUSION: On the basis of the clinical data obtained in this research, the authors suggest that the therapy by means of splinting improves the prognosis of teeth affected by periodontal disease; occlusal trauma and dental mobility cause the aggravation of periodontal lesions.

Different types of splints have been used to stabilize traumatized teeth in children. Some of these splints have compromised healing of the teeth and associated dental tissues. This article considers the ideal properties for a splint and describes a method of splinting traumatized teeth in children that meets most of the requirements of an ideal splint.
Orthodontic relapse and tooth migration are commonly observed in patients with severe postorthodontic root resorption. If conventional removable retention is not adequate, fixed splint retention is necessary. Proponents of flexible splints suggest that the difference in mobility between natural teeth and the rigid systems is responsible for the loss of cement seal in the rigid systems. Proponents of rigid splints suggest that the flexibility that allows physiologic movement of the teeth also contributes to fatigue and subsequent failure of the material in the flexible splint systems. A clinical technique for increasing retention, consequently improving the prognosis of a resin-bonded fixed splint, is described.
