“…So the volume of augmentation is maintained during healing period, therefore the need of block bone and titanium mesh is minimized; 3) Fibrin network entraps platelets and leukocytes to release growth factors, so bone regeneration and soft tissue is accelerated; 4) No biochemical additives are needed to make sticky bone; 5) Fibrin interconnection minimizes soft tissue ingrowth into the sticky bone graft. 19…”

“…18 The use of autologous leukoplakelet fibrin (PRF) in the graft process allows to enjoy its characteristics, namely in the modeling of the inflammatory response, immune response and tissue repair, tissue reorganization and angiogenesis ( Figure 3A). 19 The association of PRF with mineral biomaterials (I-PRF) facilitates handling, application and allows immediate adhesion to the receiving bed ( Figure 3B and Figure 3C). 19 The inferior layer of bone reconstruction was made with Cerasorb M ® foam soaked with PRF in an attempt to protect the inferior alveolar nerve integrity and strengthen the lower border of the mandible.…”

Purpose: The dentigerous cyst is the second most common odontogenic cyst in the jaws. These lesions are observed in routine examinations. The third molars and maxillary canines are the most affected teeth. Definition of marsupialization and enucleation techniques as well as consideration of important objective criteria for the treatment plan like cyst size, age, and proximity to anatomical structures, clinical importance of the tooth or teeth associated with the lesion and risk of bone fracture. This paper will present a case report treated by maneuver of decompression followed by enucleation and bone reconstruction. Case report: A 43-year-old female patient, Caucasian, attended the Oral-Maxillofacial Surgery consultation at Clitrofa - Centro Médico, Dentário e Cirúrgico, in Trofa - Portugal, to assess extraction of 3.8 and 4.8. On intraoral physical examination, a slight bulging of the cortical bone was noted in the region of the left external oblique line. Aspiration puncture was performed and a small amount of light-yellow liquid confirmed the cystic nature of the lesion. In a second stage, osteotomy through piezoelectric surgery was performed. The cystic capsule was excised together with the extraction of tooth 3.8 included and tooth 3.7. Bone regeneration was performed. The material obtained from the cystic cavity was sent for pathological examination, confirming the diagnosis of dentigerous cyst. During observation of the patient for twelve months, no hypoesthesia or any sign of recurrence of the lesion was observed. Conclusion: The technique preserved the neurosensory function and was effective for the enucleation and reconstruction of the lesion. Despite the clinical peculiarities of each case and the chosen treatment method, the prognosis of these lesions is favourable when appropriate therapy is used.
