Tests for local effects after implantation: Suitable to study the main physiological systems: From an ethical point of view, one sheep allows for up to 12 implants per animal, permitting to keep them alive at the end of the experiments.
B Surgical cavities after collecting the samples.
The different animal models are divided into small animals mice, rats and guinea pigmedium animals rabbits, cats, mini-pigs and dogs and large animals horses, sheep macelo goats. Surgical procedures in animals can only be developed after approval from the Ethics Committee on Animal Use at the institution where the experiments are performed.
When in confinement, ventilation systems ensuring adequate airflow to avoid excessive heat are necessary to minimize uzedw risk of heat stress. Two experimental groups were studied: All experiments have been completed without any complications regarding the animals and allowed us to evaluate hypotheses and explain their mechanisms.

The sheep is an excellent animal model for the evaluation of biomaterials for bone regeneration and osseointegration of dental implant system in dentistry and orthopedics. J Mater Sci Mater Med.
Gene Ontology GO Terms. Useful data for clinical applications in humans should be based not only on good planning and design of the experimental study, but also on adequate knowledge of the animal used, taking into account the differences with humans.
Rabbit as animal models in contemporary implant biomaterial research. The anesthetic protocol used in our group to test biomaterials and implant systems consists of premedication with acepromazine 0.
Sheep are also compelling from an ethical point of view because according to the ISO, up to 12 implants can be tested per animal, and they mwrcelo be kept alive at the end of the study, in accordance with the 3Rs principles.

Table 2 Table 2 Table showing our experiments in which sheep as animal model were used. With the current focus on animal preservation in experimental studies, research proposals should consider the replacement of animals with validated alternative methods, and the animals' wellbeing should be the primary consideration in the provision of care at all stages of the experiment 3. Dental implants in sheep tibia with a minimum of 2 cm distance separating each other.
Until the present time, we have successfully carried out forty-six surgical procedures in three different studies. However, information about their utility as an experimental model is limited. These cylindrical implants should not exceed 4mm diameter and 12mm in length and, in the case of screws-type implants, the dimensions must be 2 to 4.
