“…However, they fail to provide definitive or curative management. ( Moss and Garrett, 1984 , Dahlström, 1992 ) Poor patient compliance and technical complications in fabrication are some of the reported limitations of occlusal splint therapy ( Dunn and Lewis, 2011 , Alqutaibi and Aboalrejal, 2015 , Alqutaibi et al, 2020 ).…”

Background The available treatment options fail to provide definitive or curative management for bruxer patients rehabilitated with implant overdentures (OD). The data regarding Botulinum toxin (BTX) injection as a management strategy for bruxism remains unclear. This randomized, single-blinded, control-group, pretest–posttest prospective trial evaluated the occlusal guard and Botox injections (BTX) effectiveness in managing sleep bruxism (SB) in subjects whose one of the edentulous arches had been restored with the implant-supported OD. Methods Forty-two patients diagnosed with definite bruxism were selected, all of which had implant-retained ODs opposing natural dentition. The participants were allocated randomly to three equal groups. Participants in group I (control group) were instructed to remove the OD at night; group II was managed with conventional occlusal stents. Those in group III were given BTX injections. New ODs were constructed for all groups, and all ball attachments were replaced with a new nylon cap. A baseline assessment (one month of OD insertion) of patient satisfaction and sleep quality was conducted, and then again at 3, 6, 9, and 12 months of treatment. Subjective sleep quality was evaluated using Pittsburgh Sleep Quality Index (PSQI). Patients’ satisfaction was evaluated using Temporomandibular disorders/numeric scales (TMD/NS). Prosthodontic (mechanical) complications were recorded during the follow-up period. Results Group III showed a statistically significant improvement in patient satisfaction and sleep quality compared to the other two groups at 3, 6, 9, and 12 months follow-up period ( P = 0 0.001, 0.0001, 0.0013, and 0.0001 respectively). Regarding prosthodontic (mechanical) complications, the highest number of events was revealed in the control group. Conclusions BTX and occlusal appliances effectively improve patient satisfaction and sleep quality of Bruxer patients rehabilitated with single arch implant overdentures.

PurposeOptical tracking devices (OTDs) hold promise for enhancing patient‐centered prostheses, but their efficacy remains underexplored. This clinical study aimed to comprehensively evaluate differences in static and dynamic occlusions among occlusal appliances fabricated using optical tracking, conventional tracking, and average articulator values (AAVs), providing insights into their efficacy in clinical and research‐based practices.Materials and MethodsTwelve dentate participants aged over 25 years, with Angle Class I and II occlusal relationships, were enrolled. Occlusal appliances were fabricated by different condylar guidance values obtained by the three systems. The condylar guidance values were measured by an OTD via MODJAW, a conventional tracking device (CTD) via Cadiax compact 2, and the AAV with Bennett angle 10°, immediate mandibular lateral translation 0.5 mm, and sagittal condylar inclination (SCI) 35°. Occlusal appliances were designed using computer‐aided design (CAD) software with the measured condylar guidance values from three systems. Subsequently, standard tessellation language (STL) files were transferred to computer‐aided manufacturing (CAM) software for 3D printing with photopolymer resin. Each participant received three occlusal appliances fabricated using the three different systems. The accuracy of the systems was evaluated by accessing the clinical outcomes of the occlusal appliances. After placement, the number of contact points in maximal intercuspation position (MIP) and dynamic occlusion interferences were recorded, along with any discrepancies between designed and recorded contact points. Any anterior open bites at MIP with the appliance in place were measured from the maxillary incisal edge to the mandibular incisal edge. Statistical analysis included Kruskal–Wallis one‐way analysis of variance (ANOVA) and Mann–Whitney tests with Bonferroni correction for pairwise comparisons (α = 0.05).ResultsIn assessing static occlusion, significant differences were found in contact point discrepancies at MIP. OTD exhibited the lowest mean discrepancy of contact points compared with the original design (1.833 ± 0.312), followed by CTD (4.083 ± 0.758) and AAV (4.833 ± 1.389), with a statistical significance (p = 0.047). At the final protrusive position, OTD (0.400 ± 0.204) and CTD (1.400 ± 0.438) methods showed significantly lower discrepancies compared with AAV (3.583 ± 0.352) (p < 0.001). Additionally, the OTD method demonstrated a statistically significant reduction in anterior open bite at MIP (0.115 ± 0.044 mm) compared with AAV (0.617 ± 0.246 mm) (p = 0.049). In dynamic occlusion, OTD showed no interferences in all subjects during protrusive movement, significantly outperforming both CTD (0.917 ± 0.474) and AAV (0.417 ± 0.202) (p = 0.033). No significant differences were observed among the methods for working and nonworking side laterotrusive movements.ConclusionsThe OTD offers superior accuracy over traditional methods, with reduced discrepancies and interferences in occlusal appliance fabrication, signifying a substantial advancement in mandibular movement assessment and improving treatment efficiency and outcomes in clinical practice.
