Occlusal trauma caused by improper bite forces owing to the lack of periodontal membrane may lead to bone resorption, which is still a problem for the success of dental implant. In our study, to avoid occlusal trauma, we put forward a hypothesis that a microelectromechanical system (MEMS) pressure sensor is settled on an implant abutment to track stress on the abutment and predict the stress on alveolar bone for controlling bite forces in real time. Loading forces of different magnitudes (0 N–100 N) and angles (0–90°) were applied to the crown of the dental implant of the left central incisor in a maxillary model. The stress distribution on the abutment and alveolar bone were analyzed using a three-dimensional finite element analysis (3D FEA). Then, the quantitative relation between them was derived using Origin 2017 software. The results show that the relation between the loading forces and the stresses on the alveolar bone and abutment could be described as 3D surface equations associated with the sine function. The appropriate range of stress on the implant abutment is 1.5 MPa–8.66 MPa, and the acceptable loading force range on the dental implant of the left maxillary central incisor is approximately 6 N–86 N. These results could be used as a reference for the layout of MEMS pressure sensors to maintain alveolar bone dynamic remodeling balance.

ABSTRACT Purpose of the study: This study intends to evaluate and compare the stress distribution by three designs of prefabricated metal posts, parallel post (EG post), parallel post with coronal flare (i-post) and a tapered post (Filpost) in endodontically treated permanent maxillary central incisor. This study will help the dentists to choose the post that would generate the least stress in endodontically treated teeth. Procedure Three-dimensional (3D) finite element models were developed. The physical models include composite resin core material, dentin, endodontic post, luting cement and guttapercha. They were subjected to compressive load of 100 N at 135° angle with respect to longitudinal axis of tooth, above the level of cingulum, simulating the load condition in oral cavity and the effects of three posts on stress distribution, in endodontically treated maxillary central incisor was evaluated. Results Stress distribution was found to be better in the models having parallel post and parallel post with the coronal flare. Coronal flare has an added advantage of better fit in the root canal. Conclusion It was found that the stresses in maxillary central incisor with the parallel post with coronal flare were well distributed. How to cite this article Mengal GP, Nadgere J, Ram SM, Shah N.

ABSTRACT This study was designed to investigate the stress pattern and magnitude in periodontal ligament of maxillary central incisor for tipping and bodily tooth movement using finite element method and to determine the optimal orthodontic force required for bodily tooth movements compared to previous clinical, histologic, and laboratory studies. The three-dimensional FEM consisting of 27000 isoparametric elements of maxillary central incisor was constructed based on the average anatomic morphology given by Wheeler. Principal stresses in PDL were determined for tipping and bodily tooth movement. On application of optimal forces for tipping and bodily tooth movement, stress value seen in PDL was less, however the distribution of stress pattern coincided with the previous studies.
