Abstract: Full dental prosthesis rehabilitation on flat mandibular ridge has been a difficult case for clinicians for a long time. A huge resorption of mandibular ridge results in inadequate retention, and tounge muscle pressure, as well as lip and cheek muscles, causing a decrease in dentureâ€™s stability and retention. Neutral zone is a potential area or position where lips and cheek on one side, and tounge on the other side have balance pressure. We reported a 60-year-old male patient with chief complaints of difficulty in mastication, and loose upper and lower dentures. He also complained of denture moving during swallowing and speaking. In case management, the aim was to acquire optimum stability of the denture and arrangement of the mandibular teeth in full dental prosthesis guided by using the neutral zone. Preliminary impression was done by using alginate, then, horizontal and vertical jaw relation was recorded by using bite rim. Suction method impression technique was used to acquire functional impression. Lower denture teeth arrangement adapted the result of neutral zone impression. Acrylic denture was being contoured to adjust the natural anatomy of the oral cavity. In conclusion, the patient got a new full denture with maximum retention and stability while speaking as well as masticating. This article discussed about making of full dental prosthesis with pressure point on neutral zone impression technique on flat mandibular ridge caused by huge resorption.Keywords: flat mandibular ridge; denture stability; neutral zone; impression technique

Background: Oral health problems often leads to edentulism. Post-extraction alveolar ridge will undergo bone resorption and can be aggravated by ill-fitting denture. There are some treatment options for completely edentulous patients. However, conventional complete denture is still one of the most popular treatment options as it is predictable, cost effective, and non-invasive. There are some principles that should be followed to ensure a more comfortable and functional complete denture. Objective: The purpose of this article is to describe how a case of fully edentulous patient, with flabby tissue and flat mandibular ridge, is managed using suction method impression technique and a lingualized posterior occlusal scheme. Case Report: A female patient aged 68 years old came to the Universitas Airlangga Dental Hospital to get a new denture since her previous denture is ill-fitting and unfunctional. The mandibular alveolar ridge is flat and there is flabby tissue in the anterior region of the maxilla and mandible. Case Management: First, a preliminary impression was taken using the reversible hydrocolloid alginate impression material. Then, a bite rim was fabricated from the preliminary model. Next, the horizontal and vertical position of the mandible was determined using the bite rim. The lower bite rim was cut into 4 pillars so that a suction method impression technique could be done. A neutral zone registration was also done for guiding the lower denture teeth arrangement. The posterior occlusal scheme was arranged to be lingualized occlusion. The denture needed some minor adjustment during control. Conclusion: Suction method impression technique combined with lingualized posterior occlusal scheme will make a more retentive and stable complete denture.

Background: Atrophic mandibular alveolar ridge generally complicates prostetic restoration expecially full denture. Low residual alveolar ridge and basal seat can cause unstable denture, permanent ulcer, pain, neuralgia, and mastication difficulty. Pre-proshetic surgery is needed to improve denture retention and stability. Augmentation is a major surgery to increase vertical height of the atrophic mandible while vestibuloplasty is aimed to increase the denture bearing area. Purpose: The augmentation and vestibuloplasty was aimed to provide stability and retentive denture atrophic mandibular alveolar ridge. Case: A 65 years old woman patient complained about uncomfortable denture. Clinical evaluate showed flat ridge in the anterior mandible, flabby tissue and candidiasis, while residual ridge height was classified into class IV. Case management: Augmentation using autograph was conducted as the mandible vertical height is less than 15 mm. Autograph was used to achieve better bone quantity and quality. Separated alveolar ridge was conducted from left to right canine region and was elevated 0.5 mm from the previous position to get new ridge in the anterior region. The separated alveolar ridge was fixated by using T-plate and ligature wire. Three months after augmentation fixation appliances was removed vestibuloplasty was performed to increase denture bearing area that can make a stable and retentive denture. Conclusion: Augmentation and vestibuloplasty can improve flat ridge to become prominent.Latar belakang: Ridge mandibula yang atrofi pada umumnya mempersulit pembuatan restorasi prostetik terutama gigi tiruan lengkap (GTL). Residual alveolar ridge dan basal seat yang rendah menyebabkan gigi tiruan menjadi tidak stabil, menimbulkan ulser permanen, nyeri, neuralgia, dan kesulitan mengunyah. Tujuan: Augmentasi dan vestibuloplasti pada ridge mandibula yang atrofi dilakukan untuk menciptakan gigi tiruan yang stabil dan retentive. Kasus: Pasien wanita usia 65 tahun datang dengan keluhan gigi tiruan yang tidak nyaman. Pemeriksaan klinis menunjukkan ridge flat pada anterior mandibula, jaringan flabby dan kandidiasis, sedangkan residual ridge digolongkan menjadi kelas IV. Tatalaksana kasus: Augmentasi dilakukan karena ketinggian vertikal mandibula kurang dari 15 mm. Autograf digunakan untuk mendapatkan kuantitas dan kualitas tulang yang lebih baik. Alveolar ridge diambil dari sisi kiri dan kanan region kaninus dan digunakan 0,5 mm dari posisi awalnya untuk mendapatkan ridge baru pada region anterior. Alveolar ridge telah diseparasi difiksasi menggunakan T-plate dan ligature kawat. Tiga bulan setelah fiksasi dilepas, dilakukan vestibuloplasti untuk meningkatkan denture bearing area sehingga gigi tiruan lebih stabil dan retentive. Kesimpulan: Augmentasi dan vestibuloplasti dapat memperbaiki ridge atrofi sehingga menjadi tinggi kembali.
