PURPOSE. The midline fracture of maxillary complete dentures is a frequently encountered complication. The purpose of this study was to assess the effect of frenulum height on midline strains of maxillary complete dentures. MATERIALS AND METHODS. A removable maxillary complete denture was fabricated and duplicated seven times. Four different labial frenulum heights were tested for stresses occurring on the palatal cameo surface. The strains were measured with strain gauges placed on 5 different locations and the stresses were calculated. To mimic occlusal forces bilaterally 100 N of load was applied from the premolar and molar region. RESULTS. A statistically significant association between the height of the labial frenulum and the calculated stresses and strains was shown (P<.05) predominantly on the midline and especially on the incisive papilla. The results showed that stress on the anterior midline of the maxillary complete denture increases with a higher labial frenulum. CONCLUSION. Within the limitations of this in vitro study, it can be concluded that the stress on the anterior midline of the maxillary complete denture increases with a higher labial frenulum. Surgical or mechanical precautions should be taken to prevent short-term failure of maxillary complete dentures due to stress concentration and low cycle fatigue tendency at the labial frenulum region.

This study investigated the tongue movement during prey capture by Rana nigromaculata and the location of the frenulum linguae, which effects tongue movement. The tongue of R. nigromaculata are elliptical at the anterior and concave U-shaped at the posterior. The location of the frenulum linguae of R. nigromaculata is located at the front of the submentalis. This is due to the location of the frenulum linguae, which has significantly effects the movement and the expandability of the tongue. In terms of mobility, the tongue of R. nigromaculata and the expandability of the frenulum linguae allow the tongue to increase in length two or more times compared to immobile tongue in the other species. The time required until the swallowing movement after looking at and capturing the prey was 0.692000 seconds. Filming prey capture with a high speed camera showed that the rear part of the U-shaped tongue captures the prey with an appearance of stretching out longer to the front of tongue and turning in a reverse direction to bring the prey to the mouth.

Purpose: Median cleft of upper lip is defined as any congenital vertical cleft through the midline of the upper lip. It is uncommon, its embryological pathogenesis remains unexplained to date. The authors hereby report a rare case of median cleft of the upper lip associated with enlarged frenulum and palatal mass. This case offers some understanding of the possible embryologic development of this anomaly. Methods: A 10-month-old boy born by normal vaginal delivery at full-term had a notch in the midline of the upper lip with widened philtrum along with enlarged median frenulum, alveolar cleft, and mass of the hard palate. We performed en bloc resection of the enlarged frenulum and palatal mass and cheiloplasty under general anesthesia. Results: Histological examination revealed that the frenulum and palatal mass was consisted of fibrous tissue with normal mucous membrane. The postoperative course was satisfactory. Conclusion: A rare case of median cleft of the upper lip with associated enlarged frenulum and palatal mass was presented with proper surgical management. The surgical technique includes marginal excision of the clefted epithelium and reconstruction of orbicularis oris muscle, in addition to en bloc resection of the palatal mass and frenulotomy.

Background: The clinical significance of lip-tie, or a tethered maxillary frenulum, remains under debate. Clinicians and parents are often perplexed when deciding whether procedures available to relieve a seemingly tight or severe maxillary frenulum are needed. Purpose: No previous studies have assessed the consequences of not subjecting a tethered maxillary frenulum in newborns to surgical intervention. This study aimed to contribute the first prospective trial on this topic with a relatively extended follow-up of these newborn infants. Methods: This prospective observational questionnaire-based cohort trial was performed in a community setting and aimed to determine whether lip-tie is associated with an increased likelihood of eventual feeding or oral disorders. Results: The convenience sample comprised of 61 consecutively arriving infants with concomitant tethered frenula who were treated at the clinic for various reasons. This cohort was compared with a random sample of 66 age-matched children for a mean follow-up period of 6.42 years. Infants undergoing oropharyngeal procedures were excluded. Awareness of a deviation in oral structures was reported by 18% of the study group versus 0% of the controls. Mothers participating in the study group (24.6%) less frequently recalled painful nipples or discomfort during breastfeeding than those in the control group (47.0%) (P<0.01). There were no intergroup differences in other types of feeding difficulty, dental hygiene, pronunciation, or speech development. Conclusion: Our findings suggest that a tethered labial frenulum is not associated with an increase in breastfeeding disturbances or oral disorders. These data encourage clinicians to question the need to intervene in cases of tethered maxillary frenula.

Objectives : This study was carried out to investigate the effects of Chuna & General Oriental Method on Temporomandibular Joint Disorder Patient(Functional Lateral Mandibular Displacement) with Many Clinical Symptoms. Methods : The therapies were Chuna, acupuncture treatment and herbal medicine. We estimated the effects of treatment by measuring the length from the end of frenulum labii superioris to the frenulum labii inferioris, Visual Analog Scale(VAS) and Patient Global Assessment(PGA) before and after treatment. Results : After treatment, we confirmed these improvements: the length from the end of frenulum labii superioris to the frenulum labii inferioris changed from 10-7mm to 0-2mm, the VAS was changed from 10 to 0-2 and many clinial symptoms improved. Conclusions : These results suggusted that Chuna & General Oriental Method effected for Temporomandibular joint disorders caused many clinical symptoms.

Bony anomaly caused by lip tie is not many reported yet. There was a case of upper lip tie wrapping into the anterior premaxilla. We represent a case of severe upper lip tie of limited lip motion, upper lips curling inside, and alveolar hypoplasia. Male patient was born on June 3, 2016. He had a deep philtral sulcus, low vermilion border and deep cupid's bow of upper lip due to tension of short, stout and very tight frenulum. His upper lip motion was severely restricted in particular lip eversion. There was anterior alveolar hypoplasia with deep sulcus in anterior maxilla. Resection of frenulum cord with Z-plasty was performed at anterior premaxilla and upper lip sulcus. Frenulum was tightly attached to gingiva through gum and into hard palate. Width of frenulum cord was about 1 cm, and length was about 3 cm. He gained upper lip contour including cupid's bow and normal vermilion border after the surgery. This case is severe upper lip tie showing the premaxillary hypoplasia, abnormal lip motion and contour for child. Although there is mild limitation of feeding with upper lip tie child, early detection and treatment are needed to correct bony growth.

Ankyloglossia is the presence of a lingual frenulum, which can range from a mucous membrane band to a short and thick band and, in extreme cases, to fusion of the tongue to the floor of the mouth. The effects of such a condition, in addition to speech defects and occasionally restriction of sucking, including dental deformities, such as open bite, or even prognathism. Treatment is surgical. The preferred treatment is horizontal sectioning of the frenulum down to the lingual septum and then suturing of the mucosa. The main problem after the healing of surgical wound is adhesion and contracture. Adhesion restrict the movement of tongue like tongue-tie. Z-plasty at the site of incision can solve this problem by changing the direction of scar. We have experienced a patient with ankyloglossia with speech defect, who underwent frenuloomy by Z-plasty. So we present a surgical treatment of Ankyloglossia using Z-plasty and discuss the treatment with a review of literature.

Tongue tie is the congenital anomaly which is manifested by an abnormally short and thick lingual frenulum so that a condition outside of the range of normal anatomic or functional capability. In general, the surgical correction is the treatment of choice: release of tongue tie and closure. We compared the traditional frenotomy with laser frenotomy using Nd：YAG laser to treat 67 cases of tongue tie during a period of JAN. 1993 through Feb. 1996. The advantages of laser frenotomy were decreased blood loss and operation time. So we had a conclusion as the adequate use of laser frenotomy with suture was a good surgical procedure for correction of tongue tie.

Background and Objectives : Ankyloglossia, commonly known as tongue-tie, is the result of a short, fibrous lingual frenulum or highly attached geioglossus muscle. This condition may cause sucking and swallowing problems, articulation disorders, interference with the tongue's cleansing action, increased the potential for caries, and inability to lick the lips, play a wind instrument, and 'french kiss' Treatment is surgical procedure. In the most cases, horizontal sectioning and mucosal suture(the conventional procedure) is preferred, but in some cases, the Z-plastic procedure is effective. This study is aimed to compare the result of the two procedures. Materials and Methods : Twenty tongue-tie patients underwent operation. Ten patients were treated with the Z-plastic procedure and ten patients were treated with the conventional method randomly. We checked preoperative mobile tongue length, postoperative mobile tongue length, operation time and postoperative wound states. Results : Among the 20 cases of tongue-tie, 2 cases are excepted due to pre-operative state, thus we compared 18 cases of tongue-tie patients. There is no statistically significant difference between the two procedures except in operation time. The Z-plastic procedure apparently needs a little more operating time. Conclusion : Patients treated with the Z-plastic procedures appeared to have better outcomes, but the data shows no statistical significance except in operating time. Consequently, the Z-plastic procedure is indicated in a limited amount of cases.

Background Median cleft lip is a rare anomaly consisting of a midline vertical cleft through the upper lip. It can also involve the premaxillary bone, the nasal septum, and the central nervous system. In our current report, we present the clinical features of 6 patients with a median cleft lip and their surgical management according to the accompanying anomalies. Methods From December 2010 to January 2014, 6 patients with a median cleft lip were reviewed. Five of these cases underwent surgical correction; alveolar bone grafting was performed in a patient with a median alveolar cleft. The surgical technique included inverted-U excision of the upper lip and repair of the orbicularis oris muscle. The mean follow-up period was 20.4 months (range, 7.4-44.0 months). Results The study patients presented various anomalous features. Five patients received surgical correction, 4 with repair of the median cleft lip, and one with iliac bone grafting for median alveolar cleft. A patient with basal sphenoethmoidal meningocele was managed with transoral endoscopic surgery for repair of the meningocele. Successful surgical repair was achieved in all cases with no postoperative complications. Conclusions Relatively mild forms of median cleft lip can be corrected with inverted-U excision with good aesthetic outcomes. In addition, there is a broad spectrum of clinical features and various anomalies, such as nasal deformity, alveolar cleft, and short upper frenulum, which require close evaluation. The timing of the operation should be decided considering the presence of other anomalies that can threaten patient survival.
