Abstract Overdenture treatment provides an esthetic and functional result that allows proper access for hygiene and maintenance. For implant-retained overdentures to be successful, functional loads must be distributed optimally to the mucosa and the abutments. For this purpose, impressions must record the soft tissue supporting areas simultaneously with accurate registration of the implant components. Usually, finger pressure is used to make functional impressions. This article describes an alternate pressure-free functional impression technique for implant-retained overdentures.

AbstractPreservation rhinoplasty is a new way to reshape the nose by preserving the dorsum, nasal ligaments, soft tissue envelope, and muscles. This new concept provides the opportunity to achieve a more natural aesthetic and functional result. To achieve a good aesthetic and functional outcome while maintaining surgical safety, knowledge of the relevant anatomy is key. This is especially true for the preservation rhinoplasty technique, where a firm grasp of the anatomy of the nasal soft tissue and bony–cartilaginous framework is critical. The preservation technique is made more accessible by the open approach, which provides an opportunity for the deformity to be clearly visualized from the tip of the nose and the dorsum. Furthermore, tip plasty is easier to perform under direct vision, which is an advantage of the open approach. The goal of this article is therefore to make clear all the important anatomical structures and their relevance to the surgical steps taken when performing the open preservation rhinoplasty technique.

Superficial Area

Patients presenting with flabby or displaceable tissue continue to challenge even the most competent dental practitioners A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It can develop when hyperplastic soft tissue replaces the alveolar bone and is a common finding particularly in the upper anterior region of long-term denture wearers. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal. Under compression, the denture bearing area will exhibit localised mobility around the flabby tissue. Unless managed appropriately, such “flabby ridges” adversely affect the support, retention, and stability of complete dentures. Many impression techniques have been proposed to help overcome this difficulty Selective impression techniques have long been used in such cases, ensuring the displaceable tissue is recorded 'at rest'. Subsequently, the denture will maintain its peripheral seal during function This article presents a case report for prosthodontic rehabilitation of a patient with flabby ridge with a window tray impression technique, modified with dual trays.

Impression Technique

The purpose of this study was to evaluate the accuracy of open tray dental implant impressions when the implants are placed with varying implant angulations and depths. Four partially edentulous models were fabricated using photopolymer resin, each having different angulation and depth of the implant analogs. A total of forty open tray elastomeric impressions were made which were poured in type IV die stone (n = 10). These casts were evaluated and compared for accurate reproduction of the spatial orientation of the implant analogs in the models using digitization in three dimensions. The results were analyzed using the independent T test. Statistically significant differences were observed when the casts were compared with their respective master models. These casts had the implant replicas placed deeper within the replicated soft tissue. Making accurate impressions in partially edentulous situations with dental implants placed with varying depth and angulation is critical and clinically demanding. There is a need for future in vivo research to identify methods and materials, exploring digital impression techniques as well, in order to make precise impressions.

Clinical Conditions

Brief Background Fabrication of any dental prosthesis over a compromised residual alveolar ridge is really a challenge for prosthodontists. Fibrous or flabby ridge and highly resorbed residual alveolar ridge are two clinical situations that require special considerations during construction of any prosthesis. Mobile soft tissue and flattened alveolar ridge significantly compromise denture stability and support. There are different treatment modalities to manage these clinical conditions like surgical excision of soft tissue, ridge augmentation, modification in impression technique, etc. Materials and Methods This case report is about an old completely edentulous male patient who reported with a complaint of difficulty in chewing with his present denture. Discussion Prosthodontic management of a patient with compromised residual alveolar ridges needs special consideration . Selection of treatment modality depends on patients general health ,clinical condition of residual alveolar ridges , financial capacity and skill of the clinician A modification from conventional impression procedure was used to record maxillary flabby anterior ridge and neutral zone concept was applied for teeth arrangement to improve denture stability in atrophied lower alveolar ridge. Summary and Conclusions Surgical removal of soft tissue and implant supported prosthesis may not be possible in all situations. In that case a conservative approach using modified impression technique, neutral zone concept provides the basic triad of a successful denture prosthesis that is retention, stability and support. Key Words Flabby tissue, Window technique, Resorbed ridge, Neutral zone.

Provisional Restoration

ABSTRACT The restoration of esthetics along with maintenance of healthy gingival tissues is of utmost importance when treating the maxillary anterior region. The resorption of the residual ridge or the irregularities in soft tissue often results in an unfavorable relationship with the pontic, compromising the final esthetic outcome. Various techniques have been developed to overcome this problem, among which tissue conditioning with controlled pressure proves out to be a boon as it is noninvasive. This article presents a case of a 27-year-old male with a missing central incisor with irregular soft tissue contour. A modified ovate pontic was used and the soft tissue was conditioned with a provisional restoration followed by a specialized impression technique aiming to record the conditioned tissue without any displacement. Esthetic emergence profile was achieved in final prosthesis without any adverse consequences on a long-term follow-up. How to cite this article Quazi MA, Gade J, Lahoti K, Gade V.
