Purpose: The aim of this review is to investigate various kinds of treatments which could be performed to recover non-ideal interocclusal space to ideal state prior to implant placements. Material and Methods: According to the definition of ideal interocclusal space reported previously, orthodontic, surgical and prosthodontic treatments to resolve an excessive or insufficient interocclusal space were reviewed. Among 899 articles searched by “Pubmed”, 34 articles were screened by inclusion/exclusion criteria. Results: In cases of having an insufficient interocclusal space, orthodontic intrusion which could be the least invasive treatment, segmental osteotomy which is the most invasive, and prosthodontic restoration can be possible options for the treatment. When an excessive interocclusal space is observed, some surgical techniques can be performed, including onlay block bone graf t and distraction osteotomy. In some cases, two or more treatments may be needed to have an ideal interocclusal space for implantation. Conclusion: The interdisciplinary approach may be needed for having a predictable result after dental implantation to recover a non-ideal interocclusal space to an appropriate state. - COLLAPSE

Computer-aided design and computer-aided manufacturing (CAD/CAM) technology automates the fabrication process of implant-supported prostheses. For the CAD/CAM fabrication of implant-supported crowns, virtual models must be generated by capturing of the intraoral situation with intraoral scanners or by digitizing stone casts with laboratory scanners. This article describes a novel method for creating virtual models with impression scanning technology. By using this workflow, an implant-supported crown is rapidly fabricated without intraoral scanning and cast scanning which needs additional time for fabricating stone casts. - COLLAPSE

The treatment of oligodontia is a minimally invasive method to preserve the remaining deciduous teeth and orthodontic space closure. However, it is difficult to obtain esthetic satisfaction, and longterm prognosis can lead to various problems such as root resorption and caries. With other treatment methods, after extraction of the deciduous teeth, the implants can be placed on the partial edentulous area and the prosthesis can be restored. In this case, through the co-work with pediatrics, orthodontics, prosthodontics, and oral surgery, the treatment is established and we achieved an esthetically and functionally satisfying outcome. - COLLAPSE

This article demonstrates a case that successfully rehabilitated the maxillary anterior missing tooth area with a single-tooth implant prosthesis by integrating three-dimensional face scan data into the computer-aided design software. An extraoral transfer jig was self-invented to achieve this purpose, and a handheld face scanner app was used to accomplish economic benefits. Not only was the protocol convenient and efficient for both the patient and clinician, but it also resulted in a satisfactory outcome. - COLLAPSE

CAD-CAM (computer aided design–computer aided manufacturing) abutment is a convenient and useful prosthetic method in tilted implant installation or complicated esthetic situations. However, the dentist must design properly and order wisely so that favorable clinical results can be obtained. Herein, we investigate various factors such as connection type, prosthesis type, margin, emergence profile and gingival contact shape that must be considered in the designing CAD-CAM abutments. - COLLAPSE
