“…Chiapasco et al (17,18), Sethi and Kaus(19) reported higher survival rate and their results are similar to those of Engelke et al (1). The mean marginal bone loss is higher than the mean marginal bone loss of other methods,which were included in our study -1,586mm (14,15,16,17). Although it is lower than the marginal bone resorption described by other authors (20).…”

Longitudinal ridge split osteotomy was performed in 33 cases with horizontal alveolar bone deficit, with a sufficient apical basis , that provides primary stability of the implants. The survival rate of the implants was 87,9%. The mean marginal bone loss is 1.586mm. Bleeding on probing is registered in 45,5% of the cases. There was found no correlation between the marginal bone loss and the bleeding on probing. The complication rate was 33,4%. In 18,2% of the cases was registered fracture of the vestibular bone plate.

“…Under these circumstances, the survival of long implants decreases, and being recommended to prioritize simpler approaches. 3,4 The present study found similar stress behaviour when long implant (11 mm) was compared to short/wide implants. However, long implant presented different behaviour when compared to short implants with regular diameter (Ci5 and Ci7).…”

Short implants to support mandibular complete dentures - photoelastic analysis

This study evaluated the stress behavior around short implants in edentulous atrophic mandibles. Six groups included implants with two diameters regular and wide (4 and 5 mm) and three lengths (5, 7 and 9 mm) as follows: Ci9 (9 x 4 mm), Ci7 (7 x 4 mm), Ci5 (5 x 4 mm), Wi9 (9 x 5 mm), Wi7 (7 x 5 mm) and Wi5 (5 x 5 mm). These groups were compared to the control group CG (11 x 4 mm). The analysis was performed with the photoelastic method (n = 6). Each model comprised 4 implants with the same length and diameter connected by a chromium-cobalt bar that simulates a fixed denture. A 0.15 kg force was applied at the end of the cantilever (15 mm), and the maximum shear stress was recorded around the distal and subsequent implants. The stress values were determined, and the quantitative data (Fringes ® ) were submitted to statistical analysis with one-way ANOVA and the Dunnett test (p < 0.05). It was observed that the reduction in implant length increased stress values with a significant difference (p < 0.05) between CG Ci7 and Ci5, while the increase in implant diameter reduced the stress values without any differences found between short and long implants. Implants with 5 and 7 mm with regular diameter increased stress levels while short implants with larger diameters experienced similar stress to that of longer implants.

Of various proposed alternatives to autogenous bone, a synthetic, degradable copolymer of PLA-GLA and dextrane seems to be a promising biomaterial for maxillary sinus lift. Consecutive partially edentulous patients showing severe monolateral posterior maxillary atrophy were treated via sinus lift using PLA-GLA-dextrane copolymer as the sole filler. Delayed implant positioning was performed and cores of regenerated tissues and native bone controls were retrieved and evaluated by light and electron microscopy, histomorphometry, microhardness and qualitative X-ray analysis. Seven sinuses in 7 patients were augmented with PLA-GLA-dextrane copolymer. Six to nine months after the copolymer 'graft', 17 bone cores were retrieved: all histological sections contained newly synthesized, mineralized material and new bone in various stages of development. Histomorphometry revealed average Trabecular Bone Volume (TBV) values ranging from 51% (6 months) to 77% (9 months). Backscattered scanning electron microscopy (BSE) in experimental and control samples confirmed histology findings. Microhardness values suggested newly formed bone at nine months was not as hard as native bone. Ca and P content was similar in 9-month regenerated and native bone. Seventeen implants were inserted in the second stage of surgery: resulting Implant Success (SR) and Cumulative Success (CSR) up to 3 years were 100% following Albrektsson's criteria. Sinus lift augmentation using PLA-GLA-dextrane copolymer as the sole filler resulted in uneventful surgeries. New bone formation was evident histologically and its maturation was still in progress after 9 months. Successful, staged implant positioning was achieved in regenerated tissue. Severe horizontal and vertical residual ridge resorption in the posterior maxilla, coupled with age-linked sinus pneumatization, often represents an anatomical limitation for implant-supported fixed prosthesis in this area (1). The basic surgical technique, designed to treat such atrophy and provide adequate bone volume for implant positioning, is the "sinus lift", initially described by Boyne and co
