Gummy Smile

Digital flow has become a part of currently practiced dentistry. Virtual planning ensures predictable aesthetic and functional rehabilitation, painless postoperative recovery, and better communication with patients, thus meeting their expectations. The purpose of this case report is to demonstrate the digital planning for the correction of a gummy smile with a personalized preparation using a piezoelectric surgical guide (PerioGuide) for gingival contouring and flapless osteotomy. The guide was designed using Nemo Studio software, based on the patient’s facial aesthetic analysis, through photos, videos, and facial scanning. These images were aligned with the scan and placed over the cone beam computed gingival tomography for prediction of results, based not only on the distance from the cementoenamel junction to the bone crest but also on the best gingival margin contour according to virtual aesthetic planning. Digital planning, combined with the use of a piezoelectric device, allows for a flapless guided surgical technique for gingival contouring and osteotomy. As a result, the surgical procedure is safer, faster, and more predictable with better postoperative outcomes.

ABSTRACT This case report describes the use of a miniscrew-assisted rapid palatal expander and aligners to correct bilateral cross-bite and crowding in an adult patient with a Class III skeletal pattern. A digitally designed surgical guide was three-dimensionally printed and used to accurately insert four miniscrews into the palate; these were employed to anchor a novel miniscrew-assisted rapid palatal expander appliance without any dental anchorage. Cone-beam computed tomograms before and after miniscrew-assisted rapid palatal expander treatment demonstrated the orthopedic expansion of the maxilla without dental tipping. The patient was then fitted with aligners to correct crowding and malocclusion. This case report demonstrates the successful treatment of an adult patient with a narrow maxilla and bilateral cross-bite using a nonsurgical, conservative treatment.

Gummy Smile

A gummy smile is a form of excessive gingival display when smiling. The excessive gingival display due to altered eruption is likely to benefit from crown lengthening surgery in order to restore the esthetic smile. Case Report: The potential complications of the crown lengthening surgery include possible esthetic deformities, dentine hypersensitivity, transient mobility, and root resorption. The present case report reveals a rare complication happened after an esthetic crown lengthening surgery which was performed to correct the gummy smile of a 37-year-old female. The patient experienced dull throbbing pain and mild tender to percussion on tooth 11, 3 weeks after the surgery, and the symptoms did not improve after the composite restorations were placed at the cervical regions. Instead, the tooth was tender to percussion and palpation with a sign of coronal discoloration. Pulp necrosis was confirmed with the clinical tests. A cone-beam computed tomography was taken after the root canal treatment, and apical fenestration on tooth 11 was noted. Therefore, this case report shows the possible correlation between crown lengthening surgery on a tooth with apical fenestration and pulp necrosis, if the apical vasculature is severed accidentally during the procedure. Conclusion: A cone-beam computed tomography should be considered prior to the surgery and extra precaution during the surgery may reduce the risk of severing the apical vasculature if apical fenestration is evidenced.

RESUMO: A técnica de reabilitação com protocolos buscando a redução do número de implantes instalados tem sido realizada com excelentes taxas de sobrevivência e sucesso, além de apresentar uma grande previsibilidade e precisão dos resultados. O objetivo deste relato de caso foi descrever um protocolo reabilitador pela técnica de redução do número de implantes, com prototipagem reversa em maxila. Paciente do sexo masculino, 59 anos de idade, apresentou-se com múltiplas raízes residuais superiores e com uma condição precária de higiene oral. Após a avaliação clínica e radiográfica do paciente foi sugerido a reabilitação em protocolo all-on-six. Foram realizadas extrações de 15 raízes residuais, moldagem total superior e inferior, tomografia computadorizada, confecção de guia cirúrgico, confecção da prótese total superior, instalação de 6 implantes dentários e reabilitação protética. Esta técnica permitiu a obtenção de resultados funcional e estético satisfatórios, de rápida execução, com custo reduzido e menor morbidade.Palavras-chave: all-on-four; planejamento digital; Reabilitação protética.ABSTRACT: The technique of rehabilitation with protocols looking for the reduction of the number of installed implants has been performed with excellent rates of survival and success, besides presenting a great predictability and precision of the results. The purpose of this case report was to describe a rehabilitation protocol with the reduction of the number of installed implants, with reverse prototyping of maxilla. A 59-year-old male patient presented with residual roots of 15 all upper teeth and with a precarious oral hygiene condition. After the clinical and radiographic evaluation it was suggested an all-on-six protocol. fifteen residual roots were extracted, upper and lower total molding, computed tomography, surgical guide, superior total prosthesis preparation, 6 dental implants and prosthetic rehabilitation. This technique allowed to obtain satisfactory functional and aesthetic results with fast execution, with reduced cost and lower morbidity.Key words: All-on-four; Digital planning; Prosthetic rehabilitation.

Gummy Smile

A healthy and beautiful smile can affect appearance and confidence. One of the aesthetic problems in dentistry that is often complained of by patients is excessive gingival display (gummy smile). The excessive gingival display can be caused by several factors, one of which is altered passive eruption (APE). One of the treatments to correct gummy smile related to APE is crown lengthening. Crown lengthening can be with bone reduction (gingivectomy with bone reduction) or without bone reduction (gingivectomy). Crown Lengthening with bone reduction is a surgical procedure that aims to maintain the dentogingival complex and to improve smile aesthetics. The purpose of this case report is to determine the crown lengthening with bone reduction (gingivectomy with bone reduction) procedure as a gummy smile treatment related to APE .A23-year-old female patient, came to Dental Hospital of Universitas Airlangga with complaints of her upper gum which not in the same length and the teeth looked short, she considered her smile was less aesthetic. After conducting analyses relating to aesthetics and periodontal tissue, crown lengthening with bone reduction was chosen for this patient treatment. The treatment results are quite good, visible gingival margins that matched the gingival zenith and improved patient's smile profile. APE as the etiology of patient's gummy smile can be corrected. There are no post-surgical complications such as excessive pain and infection. A proper diagnosis, treatment plan, and good techniques can produce a harmonious smile on the patient.

Dental surgeons need in-depth knowledge of the bone tissue status and gingival morphology of atrophic maxillae. The aim of this study is to describe preoperative virtual planning of placement of five implants and to compare the plan with the actual surgical results. Three-dimensional planning of rehabilitation using software programs enables surgical guides to be specially designed for the implant site and manufactured using 3D printing. A patient with five teeth missing was selected for this study. The patient’s maxillary region was scanned with CBCT and a cast model was produced. After virtual planning using ImplantViewer, five implants were placed using a printed surgical guide. Two weeks after the surgical procedure, the patient underwent another CBCT scan of the maxilla. Statistically significant differences were detected between the virtually planned positions and the actual positions of the implants, with a mean deviation of 0.36 mm in the cervical region and 0.7 mm in the apical region. The surgical technique used enables more accurate procedures when compared to the conventional technique. Implants can be better positioned, with a high level of predictability, reducing both operating time and patient discomfort.
