A anatomia do tecido mole peri-implantar é semelhante à do dente natural, uma vez que apresenta epitélio juncional e tecido conjuntivo. O selamento peri-implantar é estabelecido pela mucosa ceratinizada que previne a migração apical da margem gengival, mantendo a arquitetura tecidual e estética vermelha ao redor dos implantes osseointegráveis. O presente trabalho objetivou relatar um caso clínico de reconstrução de tecido mole previamente a cirurgia óssea reconstrutiva para a instalação de implante osseointegrável. Após a reconstrução do tecido mole observou-se que houve um satisfatório ganho de altura e espessura tecidual. Foi obtido um volume tecidual suficiente para regularização do zênite gengival e considerável volume de mucosa ceratinizada foi obtida previamente a cirurgia reconstrutiva.Descritores: Implantes Dentários; Periodontia; Reabilitação Bucal.ReferênciasMutthineni RB, Dudala RB, Ramisetty A.

The Matrix

Background: The presence of keratinized tissue around dental implants is more than desirable either from a functional and aesthetic point of view, making soft tissue grafting a common practice in implant rehabilitation. Autogenous soft tissue grafting procedures are usually associated with high morbidity. Aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants. Methods: 15 consecutive patients underwent a vestibuloplasty and grafting, both in the mandible and the maxilla, with a collagen matrix. Results: The primary endpoint was to evaluate the resorption of the graft along with the re-epithelization grafted area. The percentage of the resorption was 44,4%, with a mean gain in vestibular height of 3 mm. Secondary endpoints evaluated the clinical appearance, the hemostatic effect and the post-operative pain. All subjects referred minimal pain with no bleeding. No adverse reaction nor infection were noted. Conclusion: This study showed that the used collagen matrix can find major interest in those patients who need a greater aesthetic outcome as the matrix has a perfect integration with the surrounding tissues. Furthermore it is strongly recommended for those patients who can bear little pain. Clinical Significance: Post-operative morbidity of autologous grafts is the biggest concern of this type of surgery. The possibility to use a soft tissue substitute is a great achievement as morbidity decreases and bigger areas can be treated in a single surgery. The present study showed the efficacy of a collagen matrix as this kind of substitute.

Objective: Septal Perforations may be asymptomatic or can cause significant problems including nasal obstruction, crusting, bleeding, whistling and in severe cases a change in nasal shape and even pain. Method: The author would like to present a single surgeon case series of septal perforation repairs, managed using an endo-nasal technique, with no external scars. There were 54 consecutive cases between 2011 and 2017. The repair was carried out using mucosal rotation flaps with an interposition graft of porcine collagen matrix. Patients were grouped according to the size of the perforation as measured at the time of the surgery. The patients were then clinically followed up for 1 year, and the recorded outcome measures were: the success of the surgical repair and the patient reported symptoms. Results: Surgical success was 70% up to 1 cm diameter, 77% from 1 to 2 cm and 82% in perforations from 2 to 3 cm in diameter. No perforation over 3 cm in diameter was successfully closed. Patients were rendered asymptomatic even if the perforation was not closed in between 81% and 91% of patients up to perforations 3 cm in size. Over 3 cm in size 50% of patients reported being asymptomatic. Conclusions: This technique is an effective and low morbidity option for patients with small to medium sized septal perforations. For perforations over 3 cm in diameter other options may be more suitable.
