“…The morphology of elastomeric impressions facilitates photoconductivity of the IOSs or digitizing physical casts precisely in subgingival preparations and undercut or apical areas. Laboratory scanners cannot register the areas of surfaces beyond the incidence of the light they emit [ 16 ]. Besides the advantages mentioned for IOSs [ 32 ], factors such as saliva and patient movements that make errors during digitization can be factors for more inclination towards scannable elastomeric materials.…”

“…Instead, with the development of scannable elastomeric impressions, we can scan them without pouring a stone cast. The difference between scannable elastomeric impressions and conventional ones is related to their color, physical characteristics, and brightness of surface material, which are hypothesized to enhance digitization [ 16 ].…”

Background The accuracy of impression techniques determines the marginal fit of fixed prostheses. Marginal accuracy plays a main role in the success and failure of treatments. This in-vivo study evaluated the marginal fit of anterior three-unit monolithic zirconia fixed partial dentures (FPDs) using conventional and scannable polyvinyl siloxane impression materials. Methods Ten patients were selected to replace the lateral teeth with a three-unit monolithic zirconia bridge. For each patient, in the first group, an impression was made with a two-step putty-wash technique using scannable polyvinyl siloxane material (BONASCAN; DMP, Greece). In the identical session, as the second group, an impression of conventional putty-wash polyvinyl siloxane was taken (BONASIL A+ Putty; DMP, Greece). The marginal discrepancy was measured through the replicas, which were cut perpendicularly within the buccolingual and mesiodistal directions. An Independent t-test was employed for data analyses (P < 0.05). Results The marginal discrepancy in a conventional method for central abutment in mid-buccal, mid-lingual, mid-mesial, and mid-distal was higher than in the scannable method but it was not significant (P > 0.05). Also, the marginal discrepancy for canine abutment in the conventional method was higher than in the scannable method, but it was not significant, either (P > 0.05). Conclusions FPDs fabricated from both scannable and conventional impression materials were not superior to each other in marginal fit for both central and canine abutments by evaluation using the replica technique.

Protetik diş tedavisinde ölçü işlemi, diş ya da implantların ve ağız için dokuların negatif formunun elde edilerek alçı ya da farklı materyaller ile çalışma modellerinin elde edilmesindeki ilk aşamadır. Ölçü aşamasında kullanılan farklı ölçü maddeleri ile ölçü yöntemleri bazı hekimlere karmaşık gelerek hatalı ölçü işlemlerine neden olabilmektedir. Ölçü aşamasında meydana gelebilecek hatalar hem restorasyonların hem de implantların prognozunu etkilemektedir. Diş hekimliğinde dijitalleşme ile dijital ölçü ve Bilgisayar Destekli Tasarım/Bilgisayar Destekli Üretim (CAD/CAM) sistemlerinin kullanımı artmıştır. Bununla birlikte hekimlerin aklında ne zaman hangi ölçü tekniği uygulanması gerektiğiyle ilgiler sorular oluşmaya başlamıştır. Bu derlemenin yazılmasındaki amaç ölçü materyalleri ile implant üstü ölçü tekniklerini güncel literatür ışığında açıklamak ve ölçü tekniği seçeneklerini hekimlerin kullanımına sunmaktır.

Recently, digital techniques have revolutionized the production of partial removable dental prostheses (PRDPs). This chapter reviews current systems for PRDP production, how they are done in clinical practice, advantages and limitations, and current literature regarding their clinical performance. Currently, several digital techniques are available in the market for PRDP production including subtractive and additive techniques. Subtractive milling technique is mainly effective for non-metal PRDP, whereas additive techniques are used mainly in metal PRDP. Digital techniques expand the range of materials that can be utilized for PRDP production, including new polymers (PEEK), and facilitate previously difficult procedures such as casting titanium PRDP, which can be produced more easily with digital methods. This review shows that available evidence suggests that these techniques have promising clinical results. Laser sintering resulted in higher patient’s satisfaction compared to conventional PRDP. However, long-term clinical trials are recommended to explore the long-term effects of these techniques. Moreover, this review showed the lack of evidence on the clinical performance of non-metal partial removable dental prostheses.
