Supernumerary teeth often cause tooth retention. The presence of supernumerary teeth, depending on their shape, number and location, can create unfavorable conditions for the development of the dental arches and occlusion, resulting in significant functional and esthetic disorders. The article presents clinical cases of patients with hyperdontia and tooth retention. Each case involves a thorough patient examination and an individual approach to the choice of treatment. The authors’ experience in treating retention caused by hyperdontia allowed a range of treatment methods to be used, depending on the functional state of occlusion, the patient’s age and the characteristics and location of the impacted and supernumerary teeth. In two patients with dentition in the early transitional period, the central incisors erupted without a doctor’s intervention within three months after the extraction of supernumerary teeth. In both cases, the subsequent orthodontic treatment aimed at correcting the torsiversion the incisors displayed upon eruption. Another case demonstrates a method of treatment that provides minimal loss of bone tissue: the supernumerary tooth were initially shifted to the alveolar bone surface and then removed. The last case describes a complete surgical-orthodontic treatment. Bone grafting was performed after the extraction of a supernumerary tooth, and an impacted tooth was moved to the newly created bone tissue. All these methods of treatment have their specific indications and can be implemented after a thorough examination of the patient.
