Patient-centered outcome measures comparing the autogenous and allogenic bone blocks in the augmentation of deficient alveolar ridges: A pilot study.

Abstract

The aim of the present study was to evaluate and compare the patient-reported experience and outcome measures (PREMS and PROMS) and three-dimensional augmentation efficacy of the autogenous and allogenic bone block grafts in deficient alveolar ridges through cone beam computed tomography (CBCT). Twenty patients were equally divided into Groups I and II treated with autogenous and allogenic bone block grafts for ridge augmentation, respectively. The radiographic parameters including the apico-coronal defect height (DH) as well as buccolingual defect depth (DD) and mesiodistal defect width (DW) at apical, middle, and cervical zone were measured using CBCT at baseline, 6 months and 1 year. The PREMS and PROMS were evaluated using Visual analogue scale (VAS) scale and questionnaire method. The mean DH, apical DD and DW, middle and cervical zone DW were significantly different between two study groups (P < 0.05). The mean apical 11.6 ± 1.91 and middle zone 9.43 ± 0.89 DD were significantly higher (in Group I as compared to Group II, with P values 0.016 and 0.004, respectively). The mean bone gains in apico-coronal DH and mesio-distal DW dimension in the apical and middle zone was significantly higher in Group I (P < 0.0001). The comparison of PROM revealed better patient satisfaction in Group II as depicted by significantly higher VAS score (P < 0.0001). Superior bone gain and reduced graft resorption was observed in Group I when compared to Group II. On the contrary, better PROMs and PREMs were obtained with the allogenic bone block augmentation.
