“…Triplett et al (2009) compared differences in the bone height and width with autogenous bone and rhBMP-2 in maxillary sinus lifts. However, this clinical model had significant features which were not considered (e. g. presence of adjacent teeth, degree of sinus pneumatization and corticalisation of the adjacent bone) and therefore this change may not be associated solely with the type of material used but due to clinical variables (Parra et al, 2017). In the authors' opinion, it is more difficult to study the real impact of biomaterials in horizontal or vertical defects of the alveolar ridge than in other situations requiring bone augmentation, such as maxillary sinus lifts.…”

Bone morphogenetic protein (rhBMP-2) is a powerful osteo-inductive growth factor widely used in bone reconstruction and both the vehicle used to administer it and the scaffold substrate could determine its success in clinical situations. The aim was to analyse the clinical behaviour of dental implants placed in single alveolar ridges with a horizontal deficiency in the maxillary anterior region that were reconstructed horizontally with rhBMP-2 and porous hydroxyapatite (HA). Inclusion criteria were both males and females, between the ages of 18 and 29 with single tooth loss of one upper incisor. Cone Beam Computed Tomography (CBCT) was used to take measurements prior to bone augmentation and again prior to the implant insertion. Surgery was carried out under local anaesthetic. In the primary procedure, bone substitute was introduced using porous HA and rhBMP-2; after 4 to 5 months, dental implant surgery was carried out and the implant placed; after 3 months of consolidation the provisional prosthesis was placed and then a definitive restoration was placed. Variables were analysed using the t-test with a p-value of < 0.05 in order to assess statistical significance. Thirteen subjects were included (6 females and 7 males). Bone augmentation resulted in a bone gain of 4.15mm (p=0.023), which was shown to be statistically significant. All of the grafts placed were successful and 13 implants were placed, using torques between 30 and 70N, without complications. For the final prostheses, 1 1 were screw retained and 2 were cemented in place. The horizontal bone augmentation using HA and rhBMP-2 is an efficient technique for single bone defects in the anterior maxillary area; clinical trials on a larger scale are needed to confirm these results.

“…To achieve stable and successful outcomes, the condition of the maxillary sinus should be healthy, and the sinus membrane must not be perforated during surgery. This technique is recommended in cases of residual bone height >5 mm, with new bone formation expected to be approximately 3 mm 15 , 16 .…”

Sinus Schneiderian membrane elevation surgery is widely performed for dental implant placement in the maxillary posterior region. With regard to sinus elevation surgery, various complications can occur and lead to implant failure. For successful implants in the maxillary posterior region, the clinician must be well acquainted with sinus anatomy and pathology, a variety of bone graft materials, the principles of sinus elevation surgery, and prevention and management of complications.

“…The quality and the quantity of the bone have to be sufficient for implant placement. Posterior maxilla often presents with insufficiently available bone for the placement of implants due to the pneumatization of maxillary sinus and resorbed ridge (1,2) . The initial implant stability is poor coupled with inadequate bone height for the implant length.…”

Volumetric Bone Change After Using Liquid Phase Concentrated Growth Factor in Open Sinus Lift Surgery: A Comparative Study

2021

Purpose: To evaluate of the volumetric bone change after using liquid phase concentrated growth factor in open sinus lift surgery .Material and methods 12 pneumatized maxillary sinuses in edentulous or partially edentulous patients were divided randomly into 2 equal groups; Group (A), augmented by alloplastic bone graft Biphasic Calcium Phosphate (BCP). Group (B), augmented with BCP mixed with liquid phase concentrated growth factor (LPCGF). Visual Analogue Scale (VAS) was used to assess pain and swelling. CBCT was used to assess the volume by measuring height × surface area of augmented bone immediate and 6 months postoperatively. Clinical follow up period was at 1 st , 2 nd day then, after one week postoperatively. Results 12 sinus , bilateral 71.4%, unilateral 28.5%, female 42.8%, male 57.2% were subjected to sinus lift surgery. Mean age was 50y and average length of residual bone was 7 mm. There was no significant difference between the two groups regarding primary wound healing with percentage of success 71.4%. VAS scale representing swelling of 42.8% in group (A) and 28.5% in group (B). Pain score show decrease gradual till one week to be zero. In comparing between two groups, percentages of change in volume was highly significant (p=0.004) between two groups; in group (A) was 29.31±13.23 while, in group (B) was 2.58±1.75. Conclusion: Use of LPCG mixed with BCP bone graft to augment the sinus with open sinus lift surgery showed less bone resorption as it represented with low percentage of change in bone graft volume at 6 months postoperative .
