Inclusion Criteria: * Adult patient ( 25 years old). * Need for extraction of an irrational tooth to be treated in the molar/premolar position of the upper/lower arch. * Presence of 2mm of keratinized gingiva. * Bone dehiscence in the alveolar walls of 2 mm. 2 mm. * Adequate amount of bone in the interradicular septum to stabilize the implant (minimum height 10 mm, minimum width 4 mm at the base of the septum). * Plaque index (FMSPI, full mouth score plaque index) \< 10%. * Non-smokers or smokers of less than 10 cigarettes per day. * Absence of systemic diseases that contraindicate implant surgery. Exclusion Criteria: * Presence of alveoli with dehiscence \>2mm. * Presence of adjacent implants. * \< 2mm of keratinized gingiva. * Presence of active infection (fistula, suppuration) at the extraction site. * Presence of apical granuloma \>2mm in diameter in the root(s) of the tooth or teeth to be extracted. * Residual bone apical to the extraction insufficient to anchor the implant. * Pregnant or lactating women. * Severe cognitive or psychiatric disorders. * Compromised general health status ( ASA IV). * Use of drugs that alter bone metabolism and healing. * Absence of manual primary stability of the implant * Bone dehiscence or fenestration after implant placement (manual rotation). * Gap 2mm between the implant and the vestibular bone wall.
