Modified Periostal Pocket Flap Technique

Modified Periostal Pocket Flap Technique: a Case Series

The aim of this study is to propose a modification of the original periostal pocket flap technique consisting in replacing the xenograft by a conglomerate which contains autologous bone obtained from the future implant site through biological drilling technique and PRGF (Plasma Rich in Growth Factors)

Study Overview

• Status: Completed
• Conditions: Bone Regeneration
• Intervention / Treatment: Procedure: Modified Periostal Pocket Flap Technique

Detailed Description

Materials and methods: 8 patients referred for implant placement and with a slight bucco-lingual (BL) width deficiency in alveolar bone were included in the study. Patients were placed dental implants and bone width was augmented by using the conglomerate mentioned above.

• Study Type: Observational
• Enrollment (Actual): 8

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: Yes
• Genders Eligible for Study: All

• Sampling Method: Non-Probability Sample

Study Population

All patients included in this case series were collected from Clinica Dental Alcalá, were operated on by the same surgeon and fullfilled the inclusion and exclusion criteria.

Description

Inclusion Criteria:

• Patients with a favorable bone density and favorable bone length but insufficient bone width that could compromise implant placement

Exclusion Criteria:

• Smokers (>10 cigarettes per day) and patients with severe systemic disease ( ASA III or IV - American Society of Anaesthesiology)

Intervention / Treatment

unique group; After local anesthesia, a full thickness flap was elevated from the lingual wall and a partial thickness flap was performed in the buccal one. After that, the buccal periosteum was detached and dental implants were placed following the biological drilling protocol, getting autologous bone particles from the implant site. Patient's blood collection was performed and the plasm obtained was poured down on a sterile container and mixed with autologous bone particles collected previously during the drilling procedure. Finally the graft was placed in the pocket prepared previously and the surgical wound was sutured in two planes.
