Porcelain Fillings (Inlay - Onlay) and Clinical Applications<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The fundamental principle in dentistry is always to preserve the natural tooth structure as much as possible. This approach, called “Minimally Invasive Dentistry,” aims for minimal intervention to the remaining intact tooth structure while repairing caries or substance losses occurring in teeth. In traditional methods, the cavity formed after cleaning the decay in the tooth was closed with either composite (white) fillings or amalgam (metal) fillings. In cases where the substance loss was excessive, the tooth was reduced, and a crown (veneer) was made. However, developing technology today offers a perfect intermediate form between filling and crowning: Porcelain Fillings.<\/span><\/p>

These restorations, prepared in a laboratory environment and designed like the missing part of the tooth, are the gold standard in cases where the substance loss is too large to be repaired with a filling but not large enough to require a crown. Following current treatment protocols in the Thrace region, K\u0131rklareli Dental Clinic Atlas Sea Dental applies these tissue-friendly restorations according to the functional and aesthetic needs of patients.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

What is a Porcelain Filling (Indirect Restoration)?\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Classic fillings are “direct” applications shaped by the physician in the patient’s mouth and completed in a single session. Porcelain Fillings, on the other hand, fall into the class of “indirect” restorations. That is, after the decay is cleaned, an impression is taken from the mouth, and the filling is prepared in a laboratory environment or with CAD\/CAM (Computer-Aided Design and Manufacturing) devices.<\/span><\/p>

These restorations are divided into two main classes according to the area they cover and whether they cover the cusps (tubercles) of the tooth: Inlay Fillings and Onlay Fillings. Both are produced from aesthetic ceramics or reinforced composites and integrated into the tooth with special adhesives (resin cements).<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Differences Between Inlay and Onlay\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

These two terms, frequently confused by patients, actually refer to the size and placement of the filling.<\/span><\/p>

  1. Inlay Fillings:<\/b> Restorations placed in the hollow area between the cusps (tubercles) on the chewing surface of the tooth. They fit into the cavity inside the tooth just like a puzzle piece. <\/span>Inlay Fillings<\/b> are preferred in cases where the cusps of the tooth are not damaged, and only the tissue in the center is lost. Their biggest advantage over standard fillings is that the contact point with neighboring teeth can be precisely adjusted in the laboratory. In this way, the problem of food impaction is minimized.<\/span><\/li>
  2. Onlay Fillings:<\/b> Restorations applied in cases where the substance loss is wider and one or more cusps of the tooth are also damaged. <\/span>Onlay Fillings<\/b> protect the tooth almost like a hat by partially or completely covering the chewing surface of the tooth. While it is necessary to cut from all sides of the tooth in the crowning process, in the onlay application, only the upper part is adjusted, and the side walls of the tooth are preserved. <\/span>K\u0131rklareli Dental Clinic Atlas Sea Dental<\/b> physicians adopt the onlay method, which protects intact walls instead of cutting the tooth circumferentially, as a principle of biomimetic (nature-mimicking) dentistry.<\/span><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Why Porcelain Fillings Instead of Classic Fillings?\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    Composite fillings are quite successful materials today, but they have a disadvantage called polymerization shrinkage (shrinking while hardening). In large fillings, this shrinkage can lead to microscopic gaps between the tooth and the filling and leakage\/secondary caries over time. Since Porcelain Fillings harden in a laboratory environment, no shrinkage occurs in the mouth.<\/span><\/p>

    Also, in terms of wear resistance, Porcelain Fillings are the material closest to natural tooth enamel. In posterior molars where chewing pressure is high, while composites may wear down and collapse over time, porcelain inlays and onlays maintain their form for many years.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
