Immediately loaded titanium implants with a porous anodised surface with at least a 36 months follow-up
No full textBackground: Results from some studies clearly suggest that immediate loading can achieve equal success rates as those found in delayed or unloaded implants. There is still a lack of knowledge about the role of surface oxide properties during the peri-implant bone healing processes.
Purpose: The aim of this study was a clinical follow-up study of immediately loaded implants with a porous anodized surface.
Materials and Methods: A total of 142 TiUnite(TM) (Nobel Biocare, Goteborg, Sweden) implants were inserted from January to September 2001. All implants have been used in fixed restorations. Fifty implants were inserted in completely edentulous mandibles, and 69 implants were inserted in completely edentulous maxillae. All 119 implants were subjected to immediate functional loading (IFL) (immediate restoration with full occlusal contact). The other 23 implants, inserted in 12 patients, underwent immediate nonfunctional loading (INFL) (immediate restoration without occlusal contact) in different anatomical configurations (single tooth, small bridges in the anterior mandible, anterior maxilla, and posterior maxilla). All 142 implants have been followed for at least 3 years.
Results: All implants appeared to be osseointegrated from a clinical and radiographic point of view. No failures were observed in the IFL and INFL groups. The implant success was 100%. The mean marginal bone loss was 0.8 and 1.0 mm at 12 and 36 months, respectively.
Conclusions: Implants with a porous anodized surface appear to work well under an immediate loading state in the long term

No full textPleomorphic lipoma (PL) is a rare benign tumor mainly located in the upper back, upper shoulders, and back of the neck in elderly men. More rarely it is located in the head and neck region and in the oral cavity. The differential diagnosis should be made with sclerosing liposarcoma and well-differentiated liposarcoma. A 59-year-old male patient was referred for the presence of a lesion involving the marginal and adherent gingiva of teeth # 5; this lesion extended into the vestibular mucosa. The lesion had a 2 cm diameter, showed no tenderness, had a hard-parenchymatous consistency, was mobile on the underlying tissues and was covered by normal appearing mucosa. Under local anesthesia, the lesion was completely removed. A free gingival graft from the palate was used to cover the defect. Microscopically, it was possible to observe mature adipocytes, spindle cells and rare ''floret-like'' cells. Lipoblasts and mitoses were absent. The definitive pathologic diagnosis was pleomorphic lipoma. No recurrences were present after a 5 years follow-up. Local excision is adequate for PL and the tumor does not recur

No full textSpindle cell lipoma is a benign tumour composed by: (1) mature fat cells; (2) spindle cells; (3) a myxoid matrix separated by thick bands of birefringent collagen. Only 14 cases have been reported in the oral cavity. The authors present the second case located in the floor of the mouth. The treatment of the lesion consists of a local excision
