Preservation of dental sockets filled with composite bovine bone: A single-blind randomize Clinical trial
The increase in human life expectation demands that medical sciences adopt an attitude focused on prevention and health promotion, to provide better quality of life. However, a large number of people continue to need restorative and rehabilitative treatments. This is no different in oral health. Brazilian public health data reported that around 70% of the Brazilian population of approximately 40 years of age present with the loss of one or more teeth . These rates rise as the age range evaluated increases. Thus, osseointegration becomes the first choice for rehabilitating these patients, because it is a safe and predictable technique both for rehabilitating single and multiple tooth losses. The end purpose is to re-establish function and esthetics. However, as a result of the etiology of tooth loss and time elapsed after extraction, accentuated alveolar bone resorption may occur . These cases may require additional procedures for reconstructing the alveolar bone, for later insertion of osseointegrated implants in a more favorable prosthetic position. Alveolar bone resorption after tooth loss is a continuous and irreversible process. The mean rate of alveolar bone resorption in the anterior maxillary region during the first year after tooth loss is around 25% of total bone volume; the reduction in alveolar bone thickness may reach up to 40-60% by the 3rd year after tooth loss . For the posterior region of the maxilla, alveolar bone loss may reach up to 50% of total volume during the course of 3 years . However, studies have pointed out that the initial volume of the posterior maxilla is twice as large as the anterior maxillathe anterior maxilla.
