Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Healthy patients; Be over 18 years old; Enjoy good systemic health; Enjoy good oral health; Have at least 2 teeth that require extraction; Need for surgery to lift bilateral sinus; Anterior teeth that require extraction and that have large alveoli to facilitate the collection of bone tissue without compromising the installation of the dental implant that will be performed concurrently; Posterior teeth that require extraction will only be used if the upper posterior teeth have a broad palatal root socket that will facilitate the collection of bone tissue without compromising the installation of the dental implant performed concurrently with obtaining the material; the lower posterior teeth have a wide distal root socket that will facilitate the collection of bone tissue without compromising the installation of the dental implant carried out concurrently to obtain the material; Maxillary sinuses free from infectious processes and / or pathologies that will harm the research result; Maxillary sinuses without major resorption and that anatomically allow the grafting of biomaterials
Exclusion criteria
Exclusion criteria: Volunteers under 18 years old; with poor oral hygiene; Sinus pathologies; Have teeth with acute infection and suppuration at the site to be filled with biomaterial; Teeth with large septa that will influence sample collection, altering histomorphological and immunohistochemical data due to the presence of native bone; Maxillary sinuses with inflammatory, infectious or tumor pathologies; Maxillary sinuses with great bone resorption that hinder the nutrition of the grafted biomaterials; Present a picture of any other oral infection; Have undergone radiotherapy of the head and neck; Be a user of bisphosphonates; Present decompensated diabetes mellitus; Pregnant woman; Present a smoking habit with a potential capacity to compromise dental implantation (greater than 10 cigarettes per day); Being of indigenous ethnicity
