ABSTRACT
BACKGROUND: Dental implants are sometimes initially placed in a wrong position leading to esthetic damage, which is difficult to solve with prosthetics. Moreover, implants placed in the anterior sector, like ankylosed teeth, are frequently found in a wrong position over time with infraocclusion because of continuous anterior alveolar growth. Different treatments have been proposed to manage the consequences of malpositioned dental implants. CASE PRESENTATION: This paper describes a surgical and orthodontic new procedure that can be used to relocate an implant in a wrong position: the Orthodontic Bone Stretching technique (OBS), which involves deep partial osteotomies combined with heavy orthodontic forces. The applied force facilitates esthetic rehabilitation with a movement towards the occlusal plane and can modify the implant axis and the gingival line alignment. This relocation is made possible thanks to a bone stretching phenomenon in the surgical area without immediate mobilization or repositioning of an alveolar segment. Three cases with the need for implant repositioning are presented here and were treated with the OBS technique. CONCLUSION: In the three cases presented, implant relocation was successfully performed with the OBS technique and the prosthetic crown was modified to improve esthetic results.

BACKGROUND: Class II division 1 is the most common malocclusion in Europe. When the overjet is severe, the risk of trauma on anterior maxillary teeth as well as the risk of being bullied at school is increased. From this point of view, early treatment reduces the risk of dental fracture and increases patient self-esteem. In another hand, MIH is frequent with a prevalence of around 15% in children with country specificity, and molars in particular are difficult to treat endodontically with good long-term results when the MIH is severe. In many cases when the third molars are present, the extraction of the affected teeth followed by an orthodontic treatment remains the best solution but requires adequate orthodontic mechanics. OBJECTIVE: The purpose of this article is to display one case of class II division1 with MIH treated by orthopaedic therapy and followed by molar extractions and fixed appliance.

Gingival recession is a complex phenomenon. Root coverage results can be predictable regarding to the anatomy of the area. This includes the width of keratinized and attached gingiva, the buccolingual dimension of both soft tissue and alveolar bone, and the position and angulation of the teeth. If the tooth is out of the envelope of the alveolar process, with alveolar bone dehiscence and low thickness of the marginal soft tissue, the recession risk is important. Many techniques have been introduced to treat gingival recession. But lots of failures are linked to tooth position. An adequate orthodontic therapy, with controlled tooth movement, can improve periodontal tissues and thus improves the esthetical outcome. In some cases, orthodontic treatment is suggested to lead to an improved periodontal condition without pre-orthodontic gingival augmentation.

Date of birth: 08/05/1954; gender: female. A. PRETREATMENT RECORDS: (10/2006; 52.6yrs). DIAGNOSIS: Skeletal Class III, normodivergent. Dental Class III with anterior and left lateral crossbite. Misalignment of the interincisal midlines with leftward deviation of the lower midline due to lateral mandibular deviation to the left. Irregular occlusal plan. Missing 16-18-28-38-48. Devitalized 26-36-46 (with apical resection of the distal root). Crowns at 36-46. TREATMENT: Fixed multiband lingual appliance (Ormco seventh generation). Mandibular levelling, correction of the incisal and mandibular lateral segment torques. Bite jump with bite turbos and recentering of the interincisal midlines by means of intermaxillary traction. B. POST-TREATMENT RECORDS: (9/2008; 54.6yrs). RETENTION: Heat-shaped Osamu-type splint and wire bonded lingually 33 to 43. C. POST-RETENTION RECORDS: (10/2009; 55.6yrs). D. CLINICAL OBSERVATION: Concave profile with prominent nose and chin. In the facial view, her face is asymmetrical and the chin is inclined to the left. Convergence of the horizontals by rotating the bi-commissural plane down and to the right. Unattractive smile showing a dark corridor on account of the tipping of the occlusal plane.
