Dr. Mohammed Zaheer Kola*, Dr Hussam Sulaiman Almadi Delayed eruption of impacted canine forcing the dislodgment of Fixed partial denture……CASE REPORT Dr. Mohammed Zaheer Kola*, Dr Hussam Sulaiman Almadi Faculty, College of Dentistry, Prince Sattam bin Abdulaziz University , Alkharj Introduction Treatment Plan Pictures Discussion Unerupted teeth, unusual eruption, transposition and malpositioning of teeth have always compromised the oral health situation. Unerupted teeth or late erupted teeth have always shown the negative effect on normally erupted teeth either by forcing the tooth from out of arch, or compromising the position. Some cases delayed eruption of teeth because of some pathological or non-pathological situation may also disturbed the teeth or prostheses which is already present in the oral cavity. This poster shall represent a clinical case where prosthesis was being dislodged by delayed eruption of canine, causing discomfort and compromised aesthetic. After the combined group discussion with different speciality and their limitation, the prostheses was removed and impacted canine was extracted to precede the placement of new prostheses. - Oral prophylaxis. Diagnostic cast & Index RCT irt 25 Orthodontic referral for impacted canines Maxillo facial surgeon for extraction of canine by palatal approach Extraction of retained deciduous canines Fabrication of new prostheses with additional abutment and intentional open bite. Prosthodontic rehabilitation for this particular clinical scenario was little confusing and challenging. As their were many option for treating this case and it was a challenge for operator to defend the approach he applied. Extrusion of canine would have been done but as discussed patient was not convinced with the duration of the treatment. The treatment rendered before was not well planned as impacted canines were ignored during diagnosis and treatment planning and also the deciduous teeth were considered as abutment for the fixed partial denture. Every dentist has its own way of approaching the treatment plan, but at the end the outcome of treatment should be best acceptable by patient for his comfort and aesthetics. Treatment Upper and lower diagnostic impression were made and diagnostic cast achieved. Index were made on diagnostic cast. Orthodontic reference is taken regarding the eruption and extrusion plan for the impacted canine. The suggestion was to remove the prostheses and extrude the teeth , mean while a temporary prostheses was planned. But duration of treatment time was one of the setback factor. The position of right canine was very deep in the bone and placed and was almost near naso antral level. When patient was explained about the treatment plan and time duration, he was not so enthusiastic. He insisted on any other approach which will restore his aesthetics as early as possible. Another approach was reviewed. Removing the prostheses, followed by extraction of both the deciduous canine and extraction of impacted canines. But keeping the buccal bone intact was major concern. The treatment plan was discussed with maxillo facial surgeon and explained the need of keeping buccal bone intact to maintain the esthetical appearance. Conclusions Treatment of ill fitting fixed partial which was forced to displaced by erupting maxillary canine was discussed in detail. Various treatment option and their restriction were reviewed. The best possible approach was applied with all the consent. Case Report Response to Treatment A male patient aged 30 years reported to the prince sattam bin abdulaziz university dental college complains of ill-fitting and dislodging fixed prostheses in upper anterior region.
