Bottom Line: The original height was 3.65 (SD 0.7) mm and the augmented sinus height was 13.8 (SD 1.4) mm after the surgery.The reduced height of grafted xenogenic material (RDL) at the implant insertion was 0.83 (SD 0.38) mm, and at the final postoperative visit was 0.91 (SD 0.25) mm, showing no significant correlation with the follow-up periods by Spearman's test (P = 0.118).In addition, no significant difference in the RDL was observed according to the site of implantation (P = 0.682).

ABSTRACT

Objectives: The aim of this study was to evaluate the clinical, radiographic and histologic results when a highly purified xenogenic bone (Laddec(®)) was used as grafting material in maxillary sinuses.

Material and methods: In fifteen patients requiring unilateral maxillary sinus augmentation, the grafting procedure was performed with Laddec(®). Forty-two implants were installed after a 6 month healing period. The height of the augmented sinus was measured radiographically immediately after augmentation and postoperatively up to 36 months. At the time of implant placement, a bone core was harvested in each patient for histological examination.

Results: The cumulative implant survival rate was 97.6%. The original height was 3.65 (SD 0.7) mm and the augmented sinus height was 13.8 (SD 1.4) mm after the surgery. The reduced height of grafted xenogenic material (RDL) at the implant insertion was 0.83 (SD 0.38) mm, and at the final postoperative visit was 0.91 (SD 0.25) mm, showing no significant correlation with the follow-up periods by Spearman's test (P = 0.118). In addition, no significant difference in the RDL was observed according to the site of implantation (P = 0.682). The mean implant marginal bone loss was 0.38 (SD 0.24) mm. Histological analysis showed the bone cores were composed of 64.72 (SD 3.44)% newly formed bone, 17.41 (SD 2.02)% connective tissue, 16.93 (SD 2.83)% residual graft particles, and 0.94 (SD 0.11)% inflammatory cells.

Conclusions: According to our data, the highly purified xenogenic bone (Laddec(®)), used as graft material in the sinus lift procedure, may create adequate bone volume, and appropriate osseointegration of dental implants.

fig1: Full thickness flap elevated to expose the alveolar crest and the lateral wall of the maxillary sinus.

Mentions: Under local anaesthesia, a crestal incision was made slightly toward the palatal aspect and throughout the entire length of the edentulous segment, supplemented by buccal releasing incisions mesially and distally. Full thickness flaps were elevated to expose the alveolar crest and the lateral wall of the maxillary sinus (Figure 1). Using a round burr under cold (4 - 5 °C) sterile saline irrigation, a trap door was made in the lateral sinus wall (Figure 2). The door was rotated inward and upward with a top hinge to a horizontal position (Figure 3). The sinus membrane was lifted with elevator instruments of different shapes until it became completely detached from the lateral and inferior walls of the sinus. Small tears in the membrane were covered with a cross-linked collagen membrane (Mem-Lok®, BioHorizons, Birmingam, Alabama, USA), before graft placement to avoid the possible complication of sinusitis from the migration of granules towards the middle meatus with its obstruction.
