“…Conventional methods for making splints have emerged and been widely used for many years [1,23,24], while digital methods have been established for less than two decades. It is known that various digital workflows of fabricating splints have been proposed in the past decade, which could be described as scanning, design and fabrication roughly [5,6,[8][9][10][11][12]. The accuracy of full arch intraoral scanning was still controversial [25,26], which has been used in fabricating splints and showed promising outcome [5,10,11,27].…”

Purpose: To evaluate the chairside time and fitness of Michigan splints fabricated with conventional method and digital method. Material and Methods: Two Michigan splints were fabricated with conventional method and digital method respectively for 16 participants. In digital workflow, the data of dentitions were obtained by model scanning. Michigan splints were then designed, occlusal surface modified with the aid of fully adjustable virtual articulator, and fabricated by 3D printing technology with light-cured acrylic resin. In conventional workflow, splints were fabricated using waxed up method and fabricated with heat-cured acrylic resin. The chairside time of insertion and occlusal adjustment were recorded. The retention and comfort were evaluated by participants using 10cm Visual Analog Scales (VAS). Highly flowable Polyvinyl Siloxane (PVS) filled the space between tissue side of splints and occlusal surface of the natural dentitions. The fitness of the splints was calculated by scanning the tissue sides of splints with and without PVS replicas respectively. All data were divided into conventional group (control group) and digital group (test group), and self-controlled method was adopted. Differences between two groups were analyzed by paired t-test. Results: There was no statistical difference in insertion time between two groups (P=0.263). Test group took less chairside time for centric (605±436s vs. 945±427 s, P=0.007), protrusive (97.0±144s vs. 246±211s, P=0.036), and excursive (25.0±101s vs. 114±465s, P=0.026) occlusal adjustment than control group. The space of test group was significantly smaller than control group (350±120μm vs. 470±90.0μm, P<0.001). No statistical difference was detected in the scores of retention, comfort at postural position and comfort at centric occlusion between two groups (P≥0.113). Conclusion: Michigan splints fabricated with digital method need less chairside time and showed better fitness than conventional method.

“…With the application of Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) technology in the dentistry, several attempts have been launched to introduce digital method to the fabrication of occlusal splints [4][5][6]. Dedem et al [5] established a fully digital and plasterless fabrication workflow of Michigan splints.…”

“…As a removable device, Splint is often used in the space and stable occlusion maintaining [ 19 , 20 ], reducing TMD pain and bruxism-related symptoms [ 21 – 23 ], or occlusal reconstruction before orthodontic treatment, surgical treatment or permanent denture restoration [ 24 – 28 ]. Space-adjustment occlusal splint belongs to an improved splint.…”

Background Overerupted maxillary molars is common in adults, which can lead to insufficient intermaxillary vertical space ,great difficulty in prosthetic reconstruction ,and cause occlusal interference in movements.To reconstruct occlusal function, it is necessary to prepare enough space for prostheses. The aim of the present study was to evaluate the effect of space-adjustment occlusal splint on overerupted maxillary molars by clinical and electromyographic signals analysis. Methods Eighteen patients with overerupted maxillary molars were selected to wear space-adjustment occlusal splint suppressing overerupted maxillary molars for three months. Satisfaction was assessed by 5-point Likert; intermaxillary vertical space and the teeth transportation distance were measured in models; clinical periodontal status were evaluated by periodontal probing depth (PPT) and bleeding index (BI); electromyographic recordings of the masseter and anterior temporal muscles were monitored by Cranio-Mandibular K7 Evaluation System. Results All the patients were satisfied with the treatment effect (Likert scale ≧ 4). The intermaxillary space in edentulous areas after treatment showed statistically significant increasing when compared with those before treatment. PPT and BI showed no significant difference. No statistically significant differences were found in electromyographic activity of anterior temporal muscles, while a reduction of muscle activity in masseter in the contralateral side were detected in post-treatment evaluations compared with pre-treatment at mandibular rest position. Conclusions Space-adjustment occlusal splint is an efficient treatment option on overerupted maxillary molars by intruding the maxillary molar to obtain adequate intermaxillary space for prostheses.
