TITLE PRE-IMPLANT SPACE MANAGEMENT OF EXTRACTED MOLARS USING CLEAR ALIGNERS: A CASE REPORTAIM The present case report will illustrate the orthodontic treatment of an adult patient using clear aligners before the rehabilitation of the extracted upper permanent molars. SUBJECTS AND METHOD A 33-years-old male patient applied for treatment with the chief complaint of the upper median diastema. He was referred by his dentist with the request of space opening prior to implant placement for previously extracted upper molars. The patient had a skeletally balanced profile (SNA=83°, SNB= 80°, ANB=3°), slightly retroclined upper and proclined lower (UI/SN=100°, IMPA=96°) incisors. The overjet was 2.5mm, the overbite was 3.2mm. The canine relationship was Class I, there was a median diastema, spaces were present between posterior teeth in the maxilla and the upper premolars were rotated. There were spaces between lower teeth and the Bolton excess was 1.18mm in favor of the lower anterior teeth.The intraoral scan was performed using iTero Element™ 2 and the virtual treatment planning was made ClinCheck Pro ® 6.0 (Invisalign); we planned to close the interdental spaces, make interproximal reduction from the lower incisors and open spaces for future dental implants in the posterior. When the first set of aligners was finished, a space remained between the upper centrals. An additional set of aligners was requested. RESULTS The interdental spaces were closed successfully. The occlusal adjustments and the implant sites preparation was made using 25 aligner pairs and one set of refinement aligners that consisted of 6 pairs. The total orthodontic treatment lasted 32 weeks. The final overbite and the final overjet were 2.5mm. The upper incisors inclination was increased (UI/SN=103°) and the lower incisors inclination was decreased (IMPA=94°). At the end of the treatment, upper and lower passive lingual retainers were bonded and Essix plates were given.The patient had implant-supported crowns for the missing teeth and came for a follow-up at 8 months after active orthodontic treatment. The results were successfully maintained in the short-term follow-up.CONCLUSIONS The occlusal corrections of an adult patient before implant placement was successfully completed using clear aligners.
