Popis: Alveolar ridge resorption following tooth extraction often renders a lateral bone augmentation inevitable. Some patients, however, suffer from severe early (during graft healing, EPatients who underwent a guided bone regeneration (GBR) were screened for inclusion according to the following criteria: (1) a relatively symmetrical maxillary arch, (2) an intact contra-lateral alveolar bone dimension, (3) the presence of a pre-operative cone-beam CT (CBCT), (4) a CBCT taken immediately after GBR, and (5) at least one CBCT scan ≥6 months after surgery. CBCT scans from different timepoints were registered and imported into Mimics software (Materialise, Leuven, Belgium). Bone dimensions of the contra-lateral site of the augmentation, representing the "individual phenotypical dimension of the alveolar crest" (IPD) were super-imposed on the augmented site and registered accordingly. As such, EA total of 17 patients (23 augmented sites) were included. After EWithin the limitations of this study the results indicate that the dimensions of a lateral bone augmentation are defined by the "individual phenotypic bone boundaries" of the patient.
