Background and Aim: Hair transplantation is the main therapeutic method for androgenic alopecia. Improvement of the hair transplant techniques with more acceptable appearance of the transplanted hair has made this method more popular.Nowadays, for more acceptable appearance of transplanted hair, every follicle is transplanted separately or in small groups which is a time consuming procedure and exposes the follicles to environmental stressors. The new device that we introduce here can be time saving and decreases the exposure time to stressors.Case report: This device was named Micro-implant and we used it for hair transplantation in a 45 years old man with androgenic alopecia. After informed consent and adequate explanations, necessary laboratory tests were performed which their results were normal. Three 10x2 cm grafts were resected from occipital area. The grafts were placed into sterile physiologic buffer rapidly and then divided by a scalpel into small pieces, each containing 1-4 follicles. These graft units were transplanted into the frontal bald area by means of the Micro-implant.Conclusion: Use of this device will reduce transplantation time notably and maintain the viability of the transplanted follicles which ensure success of transplantation.

Background and Aim: Skeletal anchorage devices such as microimplants are successful attempts to have absolute anchorage. The aim of this study was to evaluate the effect of immediate and delayed orthodontic loading on maxillary and mandibular microimplants regarding histologic responses and bone implant contact (BIC) in a dog.Materials and Methods: Thirty-two microimplants (Abso Anchor) were bilaterally placed in the mandibular premolar regions of four adult male dogs. The microimplants were divided into loaded and unloaded (control) groups. The control group had two subgroups of 4 and 8 weeks and the loaded group comprised two subgroups of immediate and delayed (after 4 weeks healing period) loading. Loaded samples were subjected to 200g load provided by Ni-Ti coil spring for 4 weeks. The decalcified specimens were prepared for histological examination under light microscope. The microimplants’ surrounding tissue was observed histologically and the bone implant contact (BIC) percentage was calculated in each sample. Three ways ANOVA was used to compare BICs in different groups.Results: Mobility was detected in two mandibular microimplants, so the survival rate was calculated as 93.7%. BIC values were not significantly different between loaded and unloaded groups, and between immediate and delayed loaded groups.Conclusion: Immediate or delayed loading of microimplants does not lead to significant difference in the bone-microimplant contact.
