24 I I case report _ biomimetic approach fromthelateralincisortothelasttoothinthearch. Transverse and vertical relationships were normal (Figs.3a–c,4a&b).Duringlateralexcursions,there was no canine guidance on both sides and trau- matic occlusion was present at the second molars. During protrusion, the incisal guidance was main- tained. Theincisaledgesofthemaxillarylateralincisors wererounded,andmidlinediastemaswerepresent in the maxillary and mandibular arches. _Treatment plan Combined orthodontic, prosthodontic, and im- plant treatment was planned, aimed at restoring aesthetics and function with the maximum pre- servation of hard tissue, while replacing the miss- ing teeth and reshaping the maxillary lateral inci- sors. It was planned to close the diastemas be- tween the teeth, restore the midline in both arches and canine guidance, and gain the space neces- sary for one premolar on each side of the maxilla and the second premolars in the mandible. The missing teeth were to be replaced with crowns supported by implants, while the shape of inci- sors was to be changed with veneers and direct composite. _Orthodontic treatment The first stage of treatment included the ortho- dontic treatment to correct the lateral crossbite, close spaces in the anterior segment and restore coincidence between the midline of the maxillary arch and the facial midline. The treatment plan also included restoring the coincidence between the maxillary midline and the line between two mandibularincisorsontheleftside.Therefore,two incisors were left on the right side, whereas on the left side the canine was moved to the position of Figs. 9a & b_Reshaping of the two maxillary central incisors (before and after).
