Title |
Post-Orthodontic Space Retention In Congenitally-Missing Maxillary Lateral Patients |
Clinical Question |
How should an edentulous lateral incisor space be prepared and maintained in preparation for restoration using a lateral incisor implant? |
Clinical Bottom Line |
Adequate space should be attained during orthodontic therapy to achieve proper M-D width dimension of the lateral incisor as well as properly retained using fixed appliance means to prevent root relapse into the edentulous space. (See Comments on the CAT below) |

#1) 20152659 | Olsen/2010 | Records ot 94 patients with at least one missing lateral incisor | Retrospective Study | Key results | 6.3mm of inter-coronal distance and 5.7mm of inter-radicular distance between the edentulous site’s adjacent central incisor and canine is recommended to ensure sufficient space prior to implant placement. Bonded restorations such as a resin-bonded bridge or bonded wire will minimize tooth/root relapse into the edentulous site during retention. | |

Comments on
The Evidence |
Radiographs were used to determine the inter-coronal and inter-radicular distances prior to implant placement. With the recent incorporation of CBCT into diagnostic imaging, a more reliable conclusion might be determined if this technology were to be used rather than traditional radiographs. |
Applicability |
This information is helpful in communicating with the restorative specialist/dentist in preparing the patient for restoration of a missing lateral incisor. Adequate space maintenance is also critical to prevent relapse and further treatment prior to implant placement. |
