Purpose: The purpose of this study was to evaluate the expression of osteogenic genes associated with bone regeneration on anodizing titanium surface. Methods:
(mm) commercially pure titanium plate was made, one group was pure titanium, second group was punched, and last group was punched and anodized by electrochemical method. Through the osteogenic cell culture model, the expression of extracellular matrix proteins, such as bone morphogenetic protein-2, bone sialoprotein, aggrecan, osteocalcin, Alkaline phosphatase, collagen I had been evaluated by Real-time polymerase chain reaction, and the morphology of growing cells was evaluated by scanning electron microscopy. Results: The attachment of mesenchymal stem cell was even and well-oriented on all Ti surfaces. The osteogene expression was increased on punching groups but, decreased on anodizing surfaces in 3 week samples. Conclusion: Punched anodizing Ti has possibility be using as a dental implant material, but further in vivo study would be needed.

Purpose: In general, the surgical treatment for mandibular retrognathism is represented by two methods, distraction osteogenesis (DO) and mandibular osteotomy surgery. The DO is mostly preferred when the degree of advancement of mandible is large. However, the postoperative stability of mandibular advancement using DO have not been actively investigated. Therefore, in the present study we have compared the postoperative stability between DO and bilateral sagittal split ramus osteotomy (BSSRO) in mandibular retrognathism. Methods: Seven patients who had been treated by DO and thirteen patients with BSSRO were included in this study. Serial lateral cephalograms were analyzed by manual tracing and the amount of the mandibular elongation was measured. To evaluate the postoperative stability, positional changes of the condylar position and B point were analyzed. Results: Mean amount of mandibular advancement was
for BSSRO group and
for DO group, respectively. There was no significant difference in age between the two groups (P>0.05). Mean follow up periods were 10.77 months for BSSRO group and 11.28 months for DO group, respectively. After mandibular advancement, mean positional changes in the condyle were
vertically for BSSRO group and
vertically for DO group, respectively. Mean change of distance from B point to Y-axis was
for BSSRO group and
for DO group, respectively. According to the condylar position and B point, there were no significant differences in postoperative stability between the two groups (P>0.05). Conclusion: There was no significant difference in postoperative stability between DO and BSSRO group according to condylar position and B point. Based on the results of the present study, it is hypothesized that DO would be a good treatment choice for severe mandibular retrognathism because DO could achieve more mandibular advancement and concurrent soft tissue elongation.

Purpose: The aim of this sturdy was to assess the prevalence and change in pathologic findings in the maxillary sinus by using preoperative and postoperative cone-beam computed tomography (CBCT). Methods: The subjects included 83 patients with maxillary sinus abnormalities who underwent orthognathic surgery between January 2010 to December 2010. The CBCT analyses were classified according to the thickness of maxillary sinus membrane; Normal (membrane thickness<2 mm), mucosal thickening (membrane thickness
and <6 mm), partial opacification (membrane thickness>6 mm but not complete), total opacification, and polypoidal mucosal thickening. The diameters of the maxillary sinus ostium on the coronal cross-sectional view were also calculated. Results: Out of 166 maxillary sinuses in 83 patients, 42 (25.3%) maxillary sinuses before surgery and 37 (22.3%) maxillary sinuses after surgery showed abnormalities. A decrease in the diameters of maxillary ostium was observed after surgery (P<0.05). However, there was no significant difference in mucosal thickness both, preoperatively and postoperatively. Conclusion: The orthognathic surgery didn't deteriorate the maxillary sinus abnormaility. Despite the low prevalence of sinus complications in orthognathic surgery, all the patients should be informed of the possibility of sinusitis that could require the surgical intervention before surgery.

Purpose: This study attempts to compare the stability of hydroxy-apatite coating implant with that of sandblasted, large-grit and acid-etched surface implant at an early state of installation. Methods: 35 implants were installed in 18 patients, who had visited hospital for implant installation. The early stability at operation, 6 weeks and 12 weeks after operation using Osstell
mentor (Integration Diagnostics, Savedalen, Sweden) and Periotest
(Siemens AG, Benssheim, Germany) were measured, and subsequently analyzed statistically. Results: OsstellTM mentor value of hydroxy-apatite coated implant (HAPTITE) was measured as
at the stage of installation,
at 6 weeks and
at 12 weeks after installation. A statistically significant increase in measurement value was observed after 6 weeks and 12 weeks than when implants were placed. In case of IMPLANTIUM (DENTIUM Co. Ltd., Seoul, Korea), the measurement value was
at 6 weeks and
at 12 weeks after installation. In addition, a statistically significant increase in the value was observed when comparative analysis of the value at after installation and 12 weeks after installation was carried out. However, no significant difference between HAPTITE and IMPLANTIUM was observed. The average measurement value of periotest
at installation of HAPTITE,
at 6 weeks and
at 12 weeks after installation. Moreover, whilst comparing the value at after installation and 12 weeks after installation, statistically significant decrease in the value was observed. In case of IMPLANTIUM, the average measurement value was measured as
at 6 weeks and
at 12 weeks after installation and no statistically significant difference was observed. Furthermore, no statistically significant difference was observed between HAPTITE and IMPLANTIUM. Conclusion: In this study, both the implants demonstrated favorable early stability at the time of measurement using Osstell
mentor and Periotest
. Moreover, based on the observed results, both HAPTITE and IMPLANTIUM are considered as potent to exhibit clinically stable and prognostic results.

Epidermolysis bullosa (EB) represents a spectrum of conditions that are characterized by blistering and mechanical fragility of the skin. There is genetic heterogeneity and marked variation in clinical phenotypes in the multiple EB disorders. The most recent classification recognizes four major EB grouping and over 30 EB subtypes. The severity of EB ranges from mild to severe skin involvement, and it can be localized or generalized. Oral features include repeated occurrence of blisters, erosions, and scars, which lead to limited mouth opening, ankyloglossia, elimination of buccal vestibule, and increased risk of oral carcinoma. Routine dental care or even normal tooth brushing might cause bullae on the oral mucosa. Occasionally, the clinician will be called upon to treat patients with EB and should therefore be aware of specific treatment modifications. we present a reviews of the literature with a case providing adequate anesthetic and surgical care.

Maxillary sinus hypoplasia (MSH) is an uncommon clinical disease that represents a persistent decrease in sinus volume, which results from centripetal reaction of the maxillary sinus walls. We present a unilateral MSH case of a 46-year-old male patient with a history of nasal obstruction and headache for 3 years. He had a history of Caldwell Luc operation (CLOP) 10 years ago, and no enophthalmos, hypoglobus or facial asymmetry. After confirming the right diagnosis of MSH, filled with bone in the computed tomography scan, hyperplastic bone was removed by the CLOP approach. The uncinate process and infundibular passage were found to be degenerated and ostium was also examined to be obstructed under endoscopic confirmation. MSH can be mistaken for chronic maxillary sinusitis because of the plain x-ray appearance, so the aggravated state of MSH can be the result of surgeon's misjudgment. With additional literature reviews, this rare experience is first introduced in our Korean oral and maxillofacial surgery field.

This is a review regarding Mulliken's Modification using the Millard rotation-advancement principle for the repair of unilateral complete cleft lip and nasal deformity. All patients underwent prior labionasal adhesion and dentofacial orthopedics with a pin-retained (Latham) appliance used for infants with a cleft of the lip and palate. Technical variations concerning the operation are described. A high rotation and releasing incision in the columella lengthens the medial labial element and produces a symmetric prolabium with minimal transgression of the upper philtral column through the advancement flap. The orbicularis oris muscle is everted, from caudad to cephalad, to form the philtral ridge. A minor variation of unilimb Z-plasty is used to level the cleft side of Cupid's bow handle, and cutaneous closure proceeds superiorly from this junction. The dislocated alar cartilage is visualized though a nostril rim incision and suspended to the ipsilateral upper lateral cartilage. Symmetry of the alar base is addressed in three dimensions, including maneuvers to position the deviated anterior-caudal septum, configure the sill, and efface the lateral vestibular web. The authors believe the technical refinements described herein contribute favorably to the outcome of repair regarding unilateral cleft lip and nasal distortion.

Microvascular reconstruction, in the oral and maxillofacial regions, is a widely accepted as the best way to overcome the complex oral cavity defects. Many patients requiring composite reconstructions have been treated previously with radiation therapy, chemotherapy, selective and/or functional neck dissection or any of these combinations. In many cases of these patients, inadequate neck vessels for the microanastomosis of free flap are available, due to a lack of recipient vessels in the neck, poor vessel quality or vessel caliber mismatch. To achieve a tension-free anastomosis, vein grafting must be considered to span the vessel gap between the free flap pedicle and the recipient neck vessels. Although most microsurgeons believed that interpositional grafts are to be avoided due to vessel thrombosis and increased number of necessary microanastomosis, we, authors have some confidence of equivalency between reconstruction with and without interpositional saphenous vein graft. The great saphenous vein, also known as the long saphenous vein, is the large subcutaneous superficial vein of the leg and thigh. It joins with the femoral vein in the region of femoral triangle at the saphenofemoral junction, and coursed medially to lie on the anterior surface of the thigh before entering an opening in the fascia lata, called the saphenous opening. For a better understanding of the great saphenous vein graft for the interpositional vessel graft in the oral cavity reconstructions, and an avoidance of any uneventful complications during these procedures, the related surgical anatomies with their harvesting tips are summarized in this review article in the Korean language.

Peripheral nerve injuries in the oral and maxillofacial regions require nerve repairs for the recovery of sensory and/or motor functions. Primary indications for the peripheral nerve grafts are injuries or continuity defects due to trauma, pathologic conditions, ablation surgery, or other diseases, that cannot regain normal functions without surgical interventions, including microneurosurgery. For the autogenous nerve graft, sural nerve and greater auricular nerve are the most common donor nerves in the oral and maxillofacial regions. The sural nerve has been widely used for this purpose, due to the ease of harvest, available nerve graft up to 30 to 40 cm in length, high fascicular density, a width of 1.5 to 3.0 mm, which is similar to that of the trigeminal nerve, and minimal branching and donor sity morbidity. Many different surgical techniques have been designed for the sural nerve harvesting, such as a single longitudinal incision, multiple stair-step incisions, use of nerve extractor or tendon stripper, and endoscopic approach. For a better understanding of the sural nerve graft and in avoiding of uneventful complications during these procedures as an oral and maxillofacial surgeon, the related surgical anatomies with their harvesting tips are summarized in this review article.

Platelet-rich fibrin (PRF) is a strong but flexible fibrin including a enrich platelet which contain growth factors and cytokines. PRF can be made very simply and requires no artificial additives unlike platelet-rich plasma. While PRF is remodeled and released in the tissue, this induces cell growth, vascularization, collagen synthesis, osteoblast differentiation and an anti-inflammatory reaction. Taking advantage of these functions, PRF can stimulate regeneration of bone and soft tissue in a diverse number of ways during the course of hemostasis, wound coverage, preservation, and reconstruction of alveolar bone. Moreover, the use of PRF to improve bone regeneration has become a recent technique in implantology. In this study, through a literature review of PRF's existing clinical applications, we classified a range of potential PRF oral and maxillofacial surgery applications including preservation of extraction sockets, guided bone graft, sinus lift, dressing and periodontal treatment. This trial gave us chance to confirm the usefulness of PRF. Recently, updated clinical studies results concerning skin and tendon wound healing have become available. These results suggest that the usage of RPF will gradually expand.
