Objectives: Balance of the body trunk is associated with jaw position, occlusal force, muscular balance and vertical dimension. Dental implants are thought to be capable of correcting balance with high reproducibility following the loss of teethIn the present study, prosthetic restorations with dental implants were analysed in terms of correlation to recovery and maintenance of the body trunk balance. Methods: A total of 14 patients were in the study. They had received implant prosthetics at our university hospital, seven for intercalary single- tooth defects of the first molars, and seven for unilateral free-ends. Occlusal information, such as intercuspal contact position and area, contact number and occlusal force, was recorded onto pressure measurement films (Dental Prescale[tm]) and converted into a numerical form by an analyser (Occluzer[tm]) six months after delivery of implant superstructures. Measurements were performed with or without superstructures in each patient, and all cases were evaluated for the influence of dental implants on body sway (Gravicorder[tm]. Bacteriological and pathological parameters of peri-implantitis were analysed in the patients who were engaged to be healthy or contracted peri-implantitis after dental implant treatment. Results: There were no differences in intercuspal contact area, contact number and occlusal force on implant delivery on both contralateral and bilateral sides of dentition, with or without superstructures in the intercalary defect group. On the other hand, implant prostheses in the unilateral free-end group showed an increase in intercuspal contact area, contact number and occlusal force on the delivery side, but not the contralateral side. Notably, intercuspal contact position and area, contact number and occlusal force for the residual teeth on the delivery side were decreased by distributing functional load to the implants. Body sway was improved and tended to be balanced not anteroposteriorly, but laterally, by dental implant treatment only in the unilateral free-end group, although not statistically significantly. Bacterial flora was detected in patients with and without dental implant prosthetics, and peri-implantitis elevated the bacterial flora that are generally observed in, and specific to, periodontitis. Conclusion: Free-end implants increased intercuspal contact area, contact number and total occlusal force, influencing not the contralateral but the implant delivery side. Improved body sway is attributed to stabilised isometric contraction. In this study, the implant prostheses of the free-end group (not intercalary) acquired symmetry in the parameters, attenuating the range of lateral body sway. Therefore, although anteroposterior sway was not influenced, free-end recovery by dental implant prostheses may be associated with stabilising isometric contraction. Peri-implantitis signified an increase in bacterial flora associated with periodontitis, but not the change in spectrum, indicating that periodontitis may be an intimate factor for peri-implantitis. In conclusion, dental implant prostheses improved intercuspal contact area, contact number and occlusal force to recover and maintain body trunk balance.

Procedure: - Incision Technique and Roll Flap Creation - Excision and Transplantation of Connective Tissue Graft Material from the Palate - Implant Placement and Fixation Procedure Contents: This video describes the preparation of an implant insertion site for placement of an individual implant at site 11 using a roll flap and free connective tissue graft technique. The procedure is designed to shape the implant insertion site and to create a secure, keratinized gingival base. Step-by-step, the operator demonstrates the incision technique, the roll flap creation procedure and the techniques used for excision, transplantation and fixation of the free connective tissue graft within the scope of implant placement.

Objectives: To evaluate the influence of bone marrow cells on bone formation in an ectopic subcutaneous model in mice.
Methods: Six BALB/c mice were divided into three groups (n = 2 in each). In all groups, a xenograft was implanted subcutaneously. In the negative control group, the xenograft was hydrated with saline solution. In the positive control group, it was embedded with osteodifferentiated adult mesenchymal stem cells derived from bone marrow. In the experimental group, the xenograft was embedded with bone marrow aspirate concentrate. After 4 weeks, the animals were sacrificed and prepared for histologic, histomorphometric and immunohistochemical analysis. The following tissues were evaluated: pre-osteoid tissue (POT), loose connective tissue (LCT) and remaining xenograft particles (XG).
Results: There was statistically significant difference (p=0.008) in POT area between the negative control group (0+0%) and the other two groups (42+11% experimental; 56+55% positive control). Similarly, there was a statistically significant difference (p=0.006) in LCT area between the negative control group (49+18%) and the other two (3+9% experimental; 0+0% positive control). There were no statistically significant differences between all three groups for XG area (p=0.143).
Conclusions:The use of a mineralised scaffold loaded with either concentrated bone marrow aspirate or with osteogenically-induced bone marrow mesenchymal stem cells favours the formation of osteoid tissue compared to scaffold alone.
