“…Numerous studies have been published on bone graft stability based on two‐dimensional imaging techniques, demonstrating a significant decrease in augmented bone height within 6‐24 months after sinus lifting . Studies have also been reported on the three‐dimensional (3D) volume stability of these grafts . Although being numerous, these studies differ substantially regarding follow‐up time, method of evaluation, bone graft material, and surgical procedures.…”

Background A sinus floor augmentation may be indicated when a lack of hard tissue impedes implant placement. Although clinically successful, evidence supporting the long‐term three‐dimensional stability of the grafted volume is scarce. Second, evidence on the patient's acceptance of this type of treatment is limited. Purpose First is to evaluate the changes in graft volume after lateral wall sinus lifting based on superimposed cone beam computed tomography (CBCT) images and then to assess patient‐reported outcome measures (PROMs) and clinical outcomes. Materials and Methods Partially edentulous patients in need of a sinus lift and fixed reconstruction on at least two neighboring implants were selected for a prospective case series. Lateral wall sinus augmentation was performed using deproteinized bovine bone mineral (DBBM) as the only filling material. Volumetric changes were quantified on the basis of a preoperative CBCT and three postoperative CBCTs (at 2 weeks, 3 months, and 2 years). PROMs and clinical parameters were registered. Results Twenty‐two patients (7 males, 15 females; mean age 59 years) participated of which three patients dropped out during the follow up. Graft volumes amounted to 1418.26 mm3 at 2 weeks, 1201.21 mm3 at 3 months, and 1130.13 mm3 at 2 years postoperative pointing to a relative graft volume stability of 79.7%. Swelling was the leading symptom during the first week. A peak in visual analogue scale scores was observed for pain, swelling, and hematoma the day of surgery and 1 day postoperation with a statistically significant decline between days 3 and 7. Hemorrhage and nose bleeding occurred in 18.2% and 27.3% of the subjects, respectively. About 95.5% of the subjects would undergo the treatment again. All implants integrated successfully and demonstrated healthy clinical conditions. Conclusion Lateral wall sinus augmentation using DBBM as the only filling material is a viable treatment concept given limited graft resorption, good patients' tolerance, and clinical outcomes.

“…First, the radiographic images were transferred to grayscale tonalities of 256. The extraction socket was then marked and converted to a histogram and finally calculated in millimetres (Alzahrani et al, 2017) reported an approximate mean loss in volume of the bone replacement material of 13.9% ± 1.9%; (Wanschitz et al, 2006) depending on the material used, the contraction in volume has ranged from 25% to 40% (Hieu et al, 2010;Cosso et al, 2014). Other studies of force loading on dental implants concluded that implant loading has a positive effect in terms of the ability of the graft to maintain its height (Nyström et al, 1993;Hieu et al, 2010).…”

Sinus floor augmentation is an effective method to regain bone height for the successful insertion of dental implants into the posterior maxilla. The aim of the study was to evaluate the behaviour of augmentation material following simultaneous or staged dental implant insertion, as visible on digital panoramic radiographs using the GNU Image Manipulation Program (GIMP). We evaluated one-stage (group 1) or two-stage (group 2) maxillary sinus floor augmentation procedures in 19 patients, using a high temperature-treated bovine porous hydroxyapatite material. Digital panoramic radiographic measurements were captured pre-operatively in both groups, pre-implant insertion in group 2, and immediately postoperatively and 6 months postoperatively in both groups. Forty parallelwalled bone-level implants were placed in a one-stage (n=18) or two-stage (n=22) protocol, with a mean residual bone height of 4.9±1.8 mm and survival rate of 100%. Mean bone height increased by 8.6±1.6 mm immediately post-implantation and by 7.9±1.7 mm after 6 months. Mean distal and mesial bone losses after abutment connection were 0.42±0.24 mm and 0.34±0.27 mm, respectively. No significant intergroup or intragroup differences between simultaneous and staged dental implant procedures were found. Our results show that the histogram tool in GIMP is useful for documentation of the area of the augmentation material used in maxillary sinus floor augmentation.

Abstract:Maxillary sinus floor augmentation procedure, aka sinus floor lift surgery, stand out within the universe of bone reconstruction given that the maxillary sinus is a closed cavity with favorable nutrition, which enables the use of biomaterials alone. Therefore, this study aimed to report and discuss the technical and biological peculiarities of Lumina-Porous® biomaterial alone in the maxillary sinus by describing a sinus lift case which presented with little remaining bone. After the graft incorporation period two implants were installed in the grafted area to provide proper patient rehabilitation.
