Over Time

This study evaluates the radiological changes in tissue height after maxillary sinus floor elevation (MSFE) using three types of calcium phosphate ceramics over a period of up to 5 years after dental implant placement. In 163 patients, MSFE was performed. Three groups of patients were distinguished and treated based on the type of calcium phosphate ceramic used and radiologically evaluated: 40 patients with β-tricalcium phosphate (β-TCP), 76 patients with biphasic calcium phosphate (BCP) 20% hydroxyapatite (HA)-80% β-TCP, and 47 patients with BCP 60% HA-40% β-TCP. Radiological measurements were performed on panoramic radiographs at several time points up to 5 years after dental implant placement. After MSFE, a slow decrease in tissue height measured over time was seen in all three study groups. Resorption of the grafted bone substitutes was more prominent in β-TCP than in BCP ceramics with an HA component (60/40 and 20/80). Loss of tissue height after 5 years was lowest in BCP 60/40 and highest in β-TCP. This radiological study shows a predictable and comparable behavior of the slow decrease in tissue height over time for all three types of calcium phosphate ceramics used in MSFE. The fraction of HA in calcium phosphate ceramics and dental implant loading seems to be beneficial for tissue height maintenance after MSFE.

Abstract Background: The present study examined the effectiveness of high-purity macro/microporous beta-tricalcium phosphate (HPMM β-TCP) as a bone grafting material for maxillary sinus floor elevation by morphometric and histopathological, histomorphometric evaluations.Methods: Ten maxillary sinus floor elevation procedures using 100% HPMM β-TCP were performed on 10 patients. Morphometric evaluation was carried out by CT imaging immediately after augmentation and prior to dental implant placement after 7 months.Histopathological and histomorphometric evaluation were carried out by bone biopsy retrieval at the time of dental implant placement 7 months after sinus floor elevation. Results: All 10 sinus floor elevations were successful. Morphometric evaluation by CT images showed that the vertical height and the volume gained by sinus floor elevation decreased 7 months after surgery. Histopathological evaluation by bone biopsy retrieval specimens showed no signs of inflammation at the newly formed bone area and the native alveolar bone area. New bone formation was observed at the cranial side from the native alveolar bone. The newly formed bone had a trabecular structure and was in intimate contact with the HPMM β-TCP material. Histomorphometric evaluation by bone biopsy retrieval specimens revealed an average new bone volume of 33.97%±2.79% and an average residual HPMM β-TCP volume of 15.81%±4.52%.Conclusions: In this study, HPMM β-TCP showed the osteoconductive properties for vertical augmentation of the atrophied maxilla by means of a maxillary sinus floor elevation procedure allowing subsequent dental implant placement after a 7-month healing period.

Abstract Background The present study examined the effectiveness of high-purity macro/microporous beta-tricalcium phosphate (HPMM β-TCP) as a bone grafting material for maxillary sinus floor elevation by morphometric, histopathological, and histomorphometric evaluations. Methods Ten unilateral maxillary sinus floor elevation procedures using 100% HPMM β-TCP were performed in 10 patients. Morphometric evaluation was carried out by computed tomography (CT) imaging immediately after augmentation and prior to dental implant placement 7 months later. Histopathological and histomorphometric evaluations were carried out by bone biopsy retrieval at the time of dental implant placement 7 months after sinus floor elevation. Results All 10 sinus floor elevations were successful. Morphometric evaluation by CT showed that the vertical height and volume gained by sinus floor elevation decreased 7 months after surgery. Histopathological evaluation of bone biopsy retrieval specimens showed no signs of inflammation at the newly formed bone area and the native alveolar bone area.
