Biomechanical characteristics of maxillary anterior incisor, conventional immediate implantation and socket shield technique - A finite element analysis and case report.

Background: To prevent the absorption and collapse of the labial bone plate of the anterior teeth, immediate implantation and socket shield technique have been increasingly applied to anterior dental aesthetic implant restoration.

Objective: To provide a biomechanical basis for implant restoration of maxillary anterior teeth, finite element analysis was used to investigate the stress peak and distribution in different anatomical sites of natural teeth, conventional immediate implantation and socket shield technique.

Methods: Three maxillary finite element models were established, including a maxillary incisor as a natural tooth, a conventional immediate implantation and a socket shield technique.

Influence of different implant designs on replacement of four teeth of the posterior free-end edentulism: Three-dimensional finite element analysis and clinic case validation.

Background: With periodontal disease having an increasing incidence, mandibular free-end edentulism caused by periodontitis is clinically more common. Finite element analysis and clinical case reports were used to evaluate the influence of different designs on the load distribution of implant prosthesis in mandibular posterior free-end edentulism.

Method: A finite element model of a mandible with posterior free-end edentulism was established.
