The lower labial frenum attached to the free gingival margin can promote local tension, resulting in tissue ischemia, promoting the development of gingival recession, as well as complicating oral hygiene, resulting in chronic inflammation. In this case, early diagnosis and surgical treatment is recommended. This is the case about surgical treatment of heavy mandibular labial frenum in pre-school child with a history of syndactyly surgery. A 5-year-old girl visited the clinic with the chief complaint of high labial frenum of the mandible. Hyperplastic lower labial frenum was attached to the free gingival margin on the primary mandibular lateral incisor area. After fifteen month follow-up, right after the eruption of the permanent lower right lateral incisor, 6 years old patient received lower labial frenectomy to prevent periodontal diseases in permanent teeth and to reestablish normal anatomic characteristics. After 2 years of follow-ups, there were no marked complications.

This study was performed to evaluate the relationship between the types of maxillary labial frenum attachment and the dental age in children. The maxillary labial frenum attachment levels were examined from the children who visited Chonbuk National University Dental Hospital between April, 2010 and December, 2013. The total number of the examined children was 320 (160 males, 160 females) between the age of 2 and 12. The types of maxillary labial frenum were categorized according to Placek's classification and each type was analyzed for its relationship with both Hellman's dental age and the eruption stage of permanent maxillary anterior teeth. The observed forms of maxillary labial frenum along with their frequency were as follows: gingival (56.3%), papillary (20.6%), mucosal (18.1%) and papillary penetrating (5.0%). The frenum form showed no significant difference due to gender (p > 0.05). From IC to IIIB in Hellman's dental age, the mucosal type increased significantly (p < 0.001). There was no significant relationship between the types of maxillary labial frenum attachment and the eruption state of permanent maxillary anterior teeth (p > 0.05).

The mandibular buccal frenum is defined as a fold of mucous membrane at the posterior labial vestibule and attaches the lips and the cheeks to the alveolar mucosa, gingiva, and underlying periosteum. The buccal frenum becomes a problem when its attachment is too close to the marginal gingiva. It may then pull on healthy gingiva, encourage plaque formation and interfere with tooth brushing. Especially, heavy buccal frenum mucogingivally results in insufficent attached gingiva, inadequate vestibular depth and high frenum attachment and also difficulty in eruption of mandibular premolar. Frenotomy, frenectomy and mucogingival surgery are used in treating heavy buccal frenum. Frenotomy with autogenous free gingival graft has been used popularly because of its stable result. But, it is difficult in younger children because of inadequate donor site, difficulty in making recipient site and behavior management. Frenotomy with apically positioned flap is considered as more efficient way for a very young child with heavy buccal frenum. Additionally, modified deep sedation with $N_2O-O_2$ can be used as an adjunct for the effective treatment outcome. Decrease in muscle pull, adequate width of attached gingiva and increased vestibular depth can be expected from this treatment approach.

The mandibular buccal frenum is a fold of mucous membrane at the posterior labial vestibule, that attaches the lips and the cheeks to the alveolar mucosa, gingiva, and underlying periosteum. The buccal frenum becomes a problem if its attachment is too close to the marginal gingiva. It may then pull on healthy gingiva, encourge plaque formation and interfere with tooth brushing. Heavy buccal frenum mucogingivally results in insufficient attached gingiva, inadequate vestibular depth and high frenum attachment and also difficulty in eruption of mandibular second premolar. Frenectomy in various forms has been used for many years to remove the influence of the frenum. Unfortunately, the results are not always ideal and there is often postoperative relapse because of muscle pull. In this treatment, frenotomy was used in conjuction with autogenous free gingival graft with the object of removing the influence of the buccal frenum and creating an adequate and stable width of attached gingiva. We observed decrease in muscle pull, adequate width of attached gingiva and increased vestibular depth in addition to progressive eruption of second premolar. Periodic follow-up is needed for evaluation of relapse, grafting gingiva and also space regaining for second premolar.

The purpose of this study was to investigate the interrelationship of the maxillary interincisal diastema, spacing and crowing to the type of superior labial frenum and the type of intermaxillary suture by analyzing histories, intraoral radiographs, orthopantomographs, intraoral slide films, and dental casts. The data for this study were compiled from 500 outpatients of the Department of Orthodontics, Infirmary of Dental College, Seoul National University. The following conculusions were obtained: 1. The occurrence of maxillary interincisal diastema in the permanent dentition decreased rapidly compared with that in the mixed dentition. And there was no sex difference in the occurrence of diastema in the both dentitions. 2. Frenum attachment remained relatively constant between the two dentitions but assumed a higher level in the permanent dentition than in the mixed dentition. 3. Except suture type D which was not yet fused completely, there was no significant difference in the distribution of suture type between the mixed dentition and the permanent dentition. 4. Frenum and suture type were highly related; frenum types 5 and 6 were associated with suture types III and V. 5. In the permanent dentition, frenum type 5 and 6 and suture types III and IV occurred more frequently in the spacing group than in the normal or crowding group. 6. The relationship between the diastema and frenum types 5 and 6 and sture types III and IV showed a strong correlation.

The distances from the center line between maxillary right and left central incisors(the dental midline) to the various anatomical landmarks were measured. Fifty five students(thirth four males and twenty one females) who have at least natural teeth including maxillary and mandibular incisors and bicuspids were examined. 1. There was statistically significant difference between the dental midline and the center line of maxillary labial frenum(p<0.05). 2. There was no statistically significant difference between the dental midline and the point of incisive papilla, philtrum line, the center line between two mandibular central incisors, and the median palatine suture line(p>0.05). 3. There was no statistically significant sexual difference among data. 4. The philtrum line showed the highest value of correspondence to the center line between two maxillary central incisors followed by the center point of incisive papilla, the center line of two mandibular central incisors, median plaltine suture line and the center line of maxillary labial frenum at the decreasing rate.

Many references report that abnormal diastema except temporary diastema existing in mixed dentition period is caused by maxilary heavy labial frenum, malocclusion, progressive periodontal disease, and loss of posterior teeth. We can diagnose patient as diastema caused by periodontal disease, especially, in case of accompanying progressively destructed anterior maxillary alveolar bone defect, and interseptal bone defect. We report Multiple disciplinary approach for diastema associated with periodontal disease. Periodontal treatment(Guided Tissue -Regeneration, alveoloplasty, bone graft), or thodontic treatment (space closure, redistribution), and the final proshodontic restoration for retention were used.

A common site of fracture in maxillary complete denture is on the anteroposterior midline that coincides with the notch for relief of the labial frenum. Various approaches to reduce the incidence of this type of fracture have been suggested. The most widely used technique is the reinforcement of acrylic resin denture base with several solid metal forms. But few comparative studies on the efficacy of metal reinforcements have been reported. This study was conducted to compare reinforcing effects of commonly available metal reinforcements, which include wire, metal mesh embedded in the denture base and metal plate affixed to the impression surface of denture base by silicoating technique. This was load on the posterior. The strain gauges were oriented perpendicular to the anteroposterior midline of maxillary polished denture surface at one labial and the four palatal sites Non-renforced denture was used as control. The results were as follows : 1. In the non-reinforced denture group, only tensile strains on the palatal polished surface were observed. The tensile strains decreased in the order of incisive papilla, posterior denture border area, mid palatal area and rugae area. Compressive strain was observed on the labial polished surface. 2. As compared with the non-reinforced denture group, the metal plate or the metal mesh reinforced denture groups showed reduced palatal tensile strains,and the metal mesh reinforcement had a better reinforcing effect than the metal plate. But both reinforced denture groups showed no difference in the amount of compressive strain on the labial polished surface when compared to the non-reinforced denture group. 3. The metal wire positioned just above the labial notch decreased the compressive strain on the labial polished surface. But the presence of metal wires in the palatal polished surface caused increase in tensile strains in the area.
