Oligodontia restored with Orthodontic treatmen, No prep tecnique and implants with bone regeneration
ALL CLINICAL CASES
Young female patient affected by oligodontia .
The agenesis affecting the deciduous teeth were present on both lateral maxillary incisors (5.2-6.2), while in the permanent ones, in addition to maxillary lateral incisors (1.2-2.2), first maxillary right and left molars (1.6-2.6), right and left maxillary canines (1.3-2.3), second left mandibular premolar (3.5), left mandibular canine (3.3), central and lateral left mandibular incisors (3.1-3.2) and lateral right mandibular incisor (4.2) were also missing. All the teeth present in the oral cavity were affected by microdontia This problem, in association with the altered passive eruption, caused difficulties in the management of the orthodontic therapy.
Orthodontic Therapy :Dott Aldo Crescini -Brescia-Italy
At the end of the orthodontic treatment, the deciduous teeth were still present in the oral cavity even if the root was completely resorbed. To partially correct the gummy smile of the patient and to reduce the altered passive eruption, crown lengthenings were carried out in both the arches Subsequently, the deciduous teeth were extracted for the final step of the treatment
Tooth implants were placed in the maxillary left and right canine regions, left mandibular premolar region, mandibular left canine region, mandibular left central incisor region.
Surgical Treatment :Dott.Carlo Tinti -Flero (Brescia)- Italy
The inter-arch space created by the increase of the DVO was used to perform occlusal veneers on the second premolars and first maxillary molars as well as on the first and second premolars and molars of the mandibular arch. The occlusal veneers were carried out without tooth preparations
The occlusal veneers were made using lithium disilicate pressed (IPS e.max Press) with thickness of 0,5 mm.
A no-prep lithium disilicate pressed veneer was made for the natural tooth (central right mandibular incisor, 4.1), while the single tooth implant (lateral mandibular right incisor, 4.2) as well as the implant-supported bridge between the mandibular left central incisor (3.1) and mandibular left canine (3.3) were performed using stratified zirconia . Central and lateral maxillary incisors were restored as the final step. The two central incisors were restored with a sandwich technique using monolithic disilicate veneers for the palatine surfaces (IPS e.max Press Ivoclar Vivadent) and stratified lithium disilicate veneers for the vestibulars .

The prosthetic rehabilitation was completed following the indications of the diagnostic wax-up without any loss of dental tissue both for the posterior and anterior teeth
