Pre-implantological treatment routines for alveolar ridge atrophy – an investigation among maxillofacial and oral surgeons in southern Germany

Abstract

Background: It is not well-known which pre-implantological procedures are preferred by maxillofacial (MFS) and oral surgeons (OS) for the narrow atrophic alveolar ridge under practice based conditions and, if different training paths in surgery lead to other pre-implantological techniques being preferred. This study aims to identify which procedures are preferred by the respective specialists in which indication. Methods: A questionnaire was sent to a total of 300 MFS and OS in southern Germany. The questionnaire examined pre-implantological procedures (bone block, bone grafting material and/or particulate autogenous bone, titanium mesh, bone split, resection) in the edentulous severely atrophic mandible and in the severely atrophic single-tooth gap. Kendall's Tau-b test was used for statistical analyses. Results: One hundred seventeen participants returned the questionnaire. 68 (58%) were OS and 49 (42%) were MFS. In the edentulous mandible, bone substitute material and resection were most preferred by both specialists. Bone blocks were statistically significantly more frequently associated with MFS and bone substitute materials with OS. Bone split was more frequently used in the atrophic single tooth gap than in the edentulous mandible. OS preferred bone blocks in the single tooth gap more often than in the edentulous mandible. MFS and OS preferred resection in the edentulous mandible significantly more frequently than in the single tooth gap. Conclusions: MFS in general prefer more invasive pre-implantological therapies with the same initial diagnosis than OS, which seems to be attributed to different training paths.

Effect of enriched bone-marrow aspirates on the dimensional stability of cortico-cancellous iliac bone grafts in alveolar ridge augmentation

“…The idea of the use of AMSCs obtained via bone-marrow aspirates and concentrates in alveolar bone grafting is not a novel idea. In the literature, several articles have focused on the use of AMSCs in different pre-implantological treatment routines for alveolar ridge atrophy with various results [ 32 ]. Kühl et al added bone-marrow aspirates and concentrates to deproteinized bovine bone mineral and investigated the grafts stability during the first 6 months after maxillary sinus lift augmentation [ 33 ].…”
