Block Technique Using SmartBone
Clinical case by Dr. Giorgio Carusi
Patient: female, 55 years old, good initial health conditionSurgical anatomic site: 45-46Pre-surgical clinical situation: bone atrophy Surgical procedure: thickness transverse recovery
SURGERYDue to its high fixation tenacity, the block is fixed with
two osteosynthesis screws to obtain a perfect primary stability
FOLLOW-UP 2 MONTHSGood osteointegration is clearly noticeable
FOLLOW-UP 4 MONTHS
biopsy for
histological
analysis
Perfect three-dimensional bone reconstruction accompanied by an
adequate bone density for the placement of two implants

X-RAY ANALYSIS 4 MONTHS
From the imagistic point of view, SmartBone® addition seems to be well integrated with a good structure and
density; the bone density around lower mini-screws has an average of 500 HU
The histological analysis of the biopsies (after 4 months from SmartBone® graft) evidences an intense new formation of bone around the SmartBone® matrix (bone with empty gaps) and several lines of new bone growth, thus highlighting a good osteoconduction of the biomaterial. SmartBone® is progressively substituted by new young bone. Inside the new bone matrix, the purple lines (growth-lines) indicate a good osteoinduction. This phenomenon is also evidenced by osteoblasts presence on the outer surface of the newly formed bone where young woven bone is present. The pictures clearly show osteocytes within the gaps and a hint of bone lamellae, therefore the bone is quite mature.
HISTOLOGICAL ANALYSIS 4 MONTHS
200 X100 X 200 X
FOLLOW-UP 1 YEARA very good bone quality around the implants
ensures a perfect stability
FOLLOW-UP 2 YEARSThere is not noticeable resorption in vertical
dimension and also the horizontal aspect of the bone density looks normal;
a good osteointegration is achieved
FOLLOW-UP 3 YEARSThe implants are surrounded by
excellent bone quality
INITIAL CONDITIONSBone atrophy
FOLLOW-UP 3 YEARSExcellent bone quality
