Abstract

Excluding third molars, mandibular second premolars are the teeth most often congenitally missing, followed by the maxillary lateral incisors. Spontaneous or orthodontic space closure, removable or fixed partial prosthesis, implant and autotransplantation may be preferred depending on the age of the patient and the condition of the occlusion as a treatment approach in such cases. This case report describes treatment of mandibular midline correction with fixed mechanics after the extraction of permanent mandibular left 1. premolar in a 13-year-old male patient

Unilateral Daimi Mandibular İkinci Premolar Eksikliği: Olgu Sunumu

Abstract

Üçüncü molarlar hariç maksiller laterallerden sonra en sık karşılaşılan diş eksikliği olguları mandibular ikinci premolar eksikliğidir. Böyle olgularda tedavi yaklaşımı olarak hastanın yaşına ve oklüzyonun durumuna göre; spontan veya ortodontik boşluk kapatma, hareketli veya sabit parsiyal protezler, implant ve ototransplantasyon tercih edilebilir. Bu olgu sunumunda; mandibular sağ 2. premolar eksikliği olan ve süt 2. moların erken çekimi sonucu boşluğun spontan kapandığı gözlenen 13 yaşındaki erkek hastada orta hat sapmasının sol 1. premolar çekimiyle düzeltilmesi sunulmaktadır
