“…Examination of statistical significance of the differences between the mean values of implant mobility 3 months after immediate insertion into the extraction alveolus according to the four protocols of guided bone regeneration showed that there is no significant difference between the protocols. Rotter et al (1996) used Periotest to examine patients with 26 implants, 15 of which were loaded progressively and 11 were left without load untitil final prosthetic restoration. The worst results of stability of dental implants are recorded with the sample where protocol IV (RBDM, resorbable membrane with bovine origin) was applied.…”

The effects of different levels of dietary protein content and population density in growing pheasants, up to the age of 42 days, on production results and mortality have been studied in this paper. The experiment was set as a two factorial study (2 x 2). Factor A was the influence of crude proteins in the diet (A1 = 26% up to 4 weeks of age and 20% from 4 up to 6 weeks of age; A2 = 30% crude proteins up to 4 weeks of age and 24% from 4 up to 6 weeks of age). Factor B was the population density (B1 = 450 and B2 = 550 birds/group). The total number of birds in the trial was n= 2000. Body mass was measured at hatching, 15 and 42 days of age. Up to 15 days of age the pheasants were housed in cages, but thereon they were reared under floor conditions with free access to outdoors. The highest body mass measured at 42 days of age (457.07 g) and the utmost daily body mass increase (4.22 for the first period of growth and 13.31 for the second) was achieved by the pheasants which were fed a diet with the highest protein content (30% in the first stage and 24% in the second) and reared at a lower population density (450 birds/group). These differences were significant (p<0.01). On comparison with the available literature data the mortality was at a satisfactory level (1.27 - 3.00%) and was not influenced by the studied factors. The mortality values were numerically higher for all treatments for the period up to 15 days (0.73 - 2.70%) compared to the period from 15 up to 42 days of age (0.44-1.00%). Based upon the obtained results and the previously published literature data it can be concluded that feedstuff protein content is the key factor required in order to obtain satisfactory final body weight and subsequently good quality material for the repopulation of hunting grounds

“…Gradual loading has been suggested as a way to improve the success of endosseous implants during the initial loading period. 24,25 In a previous study by Storey,26 immediate loading of the premaxillary suture at ∼2.5 N in rabbits The distance between the implants was measured twice daily for 4 days after load adjustment and weekly thereafter. As specified, multiple fluorochrome labels were given to mark the sites of bone mineralization (Table I).…”

Osseointegrated implants have a large potential for diverse clinical applications, including support for sutural expansion and facial prostheses. The objectives of this study were to evaluate: (1) the histomorphometric response of thin cortical bone to implant placement and (2) whether loading of the bone surrounding these implants affects osseointegration as evaluated by histomorphometry. Eighteen New Zealand White rabbits had two titanium implants placed bilaterally in the anterior surface of their nasal bones. The rabbits were divided into an unloaded control group, one experimental group loaded at 1 Newton (N), and another loaded at 3 N. Fluorescent labels were used to mark areas of active bone formation. All rabbits were euthanized after 12 weeks of loading. Stereological point-hit and line-intercept methods were used to measure bone volume, direct bone-implant contact, new bone volume, and bone turnover rate in the bone surrounding the implants. All the implants remained stable during the loading period. A factorial ANOVA with repeated measures was used to compare the variables. The only significant difference among the three groups was a higher bone volume in the lateral coronal far region in the control group (p < 0. 05). Within all groups, bone volume (p < 0.002), turnover rate (p < 0.001), and percent of new bone (p < 0.05) were higher within 1 mm of the implant compared to 1-3 mm away. This may be due to the increased stress and strain in the bone adjacent to the implant. This study indicates that there are no detrimental effects of loading on osseointegration when implants placed in the thin facial cortices are used as anchors for sutural expansion.
