Abstract
In adult interdisciplinary treatments with using dental implants, limited orthodontic treatment, especially orthodontic extrusion (OE), offers many benefits by both correcting teeth alignment and by contributing to the regeneration of periodontal tissues. However, orthodontic procedures carry some risks and unpredictabilities that might compromise tooth and/or periodontal tissue health. Especially in complex cases, it is difficult to decide which orthodontic treatment modalities should be combined, in what sequences they should be applied, and what their force systems and treatment times are.To achieve optimum results, some cases require two or more OEs to the same site being carried out at different times while taking the treatment effects into consideration. Such staged OE offers minimum intervention and maximum efficiency. In this case report, OE was first applied for orthodontic extraction. After bone regeneration followed by an implant placement and another surgical operation, a second OE was applied to align the inclination of an adjacent tooth. As a result, a predictable prognosis of implants as well as greatly improved esthetics and periodontal tissue health were achieved.
Highlights
Adjunctive orthodontic treatment for adults is tooth movement that is carried out to facilitate other dental procedures necessary to control disease, restore function, and/or enhance appearance [1]
Several studies have reported that orthodontic extrusion (OE) has many benefits in adult interdisciplinary treatment [3,4,5,6]
Because OE is regarded as being simpler and easier than comprehensive orthodontic treatment, this treatment can be mistakenly considered simple and completed without careful planning, which can lead to an unsatisfactory clinical outcome
Summary
Adjunctive orthodontic treatment for adults is tooth movement that is carried out to facilitate other dental procedures necessary to control disease, restore function, and/or enhance appearance [1]. The sequence in which they are applied, the force system, and their treatment time must be considered [10] In this case report, two LOTs were applied to the same site at different times, along with tooth extraction and guided bone regeneration followed by implant. The right maxillary central incisor had previously been restored with a porcelain veneer, while the right lateral incisor was inclined labially and distally. This resulted in spaces of 1.5 and 1.0 mm on the mesial and distal proximal area of the central incisor, Fig. 5 Placement of an implant and GBR (a frontal view, b occlusal view). The treatment plan consisted of the following items: Initial preparation with scaling and root planing
