Immediate Placement of Anterior Maxillary Single-Tooth Implant : Literature Review

1 Immediate Placement of Anterior Maxillary Single-Tooth Implant : Literature Review Hsiao-Wei Lin Master Institute,School of Dentistry National Yang-Ming University Ming-Lun Hsu Professor and Chairman Department of Dentistry National Yang-Ming University Tze-Cheung Yeung Attending prosthodontist, Department of Stomatology, Taipei Veterans General Hospital Traditional guidelines suggested that 2 to 3 months of alveolar ridge remodeling following tooth extraction and an additional 3 to 6 months of load-free healing after implant insertion are needed for osseointegration to take place. However, nowadays immediate placement and immediate loading do not interfere the process of osseointegration. To achieve osseointegration, the level of micromotion should be kept below a certain tolerance threshold. Upper anterior single immediate placement of dental implants at the time of tooth extraction has yielded favorable and predictable results. Advantages include better bone and soft tissue preservation, reduced postoperative pain, significant reduction of clinical chair time, and greater patient acceptance. Apart from time gain, another rationale for immediate implantation and provisionalization is the potential to maximally preserve hard and soft tissues, which may be beneficial to the esthetic treatment outcome. The aim of the present literature review was to evaluate the outcome of immediate implantation and provisionalization to replace single maxillary tooth at the esthetic zone.
