•Ante’s Law•

The pericemental area of all abutment teeth should be equal to or greater than the pericemental area of teeth being replaced.

Types of occlusion (Bite)🦷

A crossbite is a malocclusion (bite problem) where the top teeth and bottom teeth do not come together or bite in the correct position.

A new clinical case by our expert of the group Dr Mohammed Ali Fadhil

Description:
Single discolored tooth presents a unique challenge for color change and the clinician must be aware of the basic principles of changing the color of one or more teeth in order to implement a successful treatment plan.
Treatment options for discolored teeth may include:
1. Single crown.
2. Indirect veneer.
3. Direct veneer.
4. Bleaching which is the most conservative option to be considered, but the potential for a successful outcome varies based on the cause and extent of the discoloration.
Direct composite resin veneer is the direct application of a thin layers of composite over the entire labial aspect of a tooth in order to modify the contour and/or shade. With experience and using a stratified technique composite veneer can be highly aesthetic and more conservative that full coverage crown.
There are two principal ways in which direct composite (i.e., whether used as a veneer over the entire labial surface or used selectively in isolated areas of the labial surface) can be used in managing the single discolored tooth:
1.Masking the discoloration: This is where one or several shades of composite resin are used to camouflage the underlying darkened tooth shade. For severe discolorations, a resin-based opaque layer placed over the discolored areas of tooth may be required. This is then covered with dentine and enamel shades to match the adjacent teeth.
Various stains and special effect composite shades giving fluorescence, translucency and opalescence to resin restorations provide opportunities to harmonize discolored teeth with adjacent ones.

“ By ensuring that different substrates are not connected too early while the dentin bond is maturing, the hybrid layer is able to form in a stress-free environment. This relates to the concepts of Hierarchy of Bondability (HOB) and Decoupling With Time (DWT)”

Another case involved a broken incisor.by Dr Ivan Raychev  The fracture was clean, and the fragment fit perfectly, simplifying the adhesive cementation process. However, the pulp was exposed. It had been exposed for about an hour. The patient, an 11-year-old, was treated with the goal of preserving pulp vitality. After one month, pulp vitality tests yielded positive results. Cementing the broken fragment back in place was determined to be the easiest method to restore the tooth’s natural aesthetics and functionality.

DENTISTRY ILLUSTRATED STILL 2 : Factors to consider while restoring root filled teeth

The various factors that influence the success rates, the confounding data and the lack of longitudinal studies comparing different treatment strategies make it rather difficult to create a definitive decision tree for restoring these teeth. However some of the illustrated factors could be applied clinically in our treatment to result in a predictable outcome.

Can anyone have an explanation?😳
What is that??

Composite resin restoration following BIOMIMETIC PROTOCOLS

🔘 There are 3 types of incremental lines: Daily incremental lines (cross striation), striae of Retzius and neonatal lines.
____________________
🔷️ Appearance :
When viewed microscopically in cross-section, they appear as concentric rings. In a longitudinal section, they appear as a series of dark bands. The presence of the dark lines is similar to the annual rings on a tree. They are named after Swedish anatomist Anders Retzius.
🔹️In the longitudinal section of a tooth. these lines appear near the dentin. They bend obliquely near the cervical region. They curve occlusally near the cuspal regions or the incisal regions.
🔹️Produced during the second stage of enamel calcification, also known as the maturation stage, ameloblasts produce matrix and enamel at the rate of 4 micrometers per day; however every fourth day there is a change in development. Brownish lines, the striae of Retzius, develop as a result of a change in the growth process. Macroscopically, these lines can be seen on the labial surface or lip side of anterior or front teeth as horizontal lines on the tooth crown, also known as perikymata or “imbrication lines” .
____________________
🔶️ Causes : 
Occasional darker striae or grooves of Retzius result from systemic disturbances in the human body. For example, a fever can cause some lines to appear darker than those surrounding them. Normally, amelogenesis involves a period of enamel matrix formation and a rest period. In case of any disturbance, the rest periods are prolonged and occur close to one another. Consequently, the line of Retzius appears broader and much more prominent, often presenting a brownish colour under the microscope. The neonatal line is the darkest band, which represents the disrupted enamel formation due to the stress of being born.

🔸️The formation of the striae of Retzius results from a constriction of Tomes’ processes when the activity of ameloblasts – cells only present in laying down enamel – is narrowed in conjunction with an increasing process of interrod enamel development. The striae of Retzius often extends from the Dental-enamel junction to the outer surface, ending in shallow pits known as perikymata.

⚠️ NON-CARIOUS CERVICAL LESION- due to tension (abfraction) ‼️ - with pulp involvement

🔍Produced by the concentration of energy transmitted during occlusal contacts or parafunctional habits. (Soares & Machado 2021)

✍🏼It has been proven that during abfraction, the rupture of chemical bonds between the hydroxyapatites present in the inorganic portion of enamel and dentin is promoted, these spaces being later invaded by water molecules that will prevent the reestablishment of chemical bonds and contribute to greater susceptibility to fracture and chemical degradation (Grippo 1991 - Lee & Eakle 1984)

By• .melissa_seibert Ceramic onlay preparation requires critical thought. No single onlay preparation is the same. Rather than doing the same preparation each time you have to consider what is most appropriate for that specific case.

The final post in a series about tips. This deep dive started when I was trying to figure out the best tip for sealants. And then I started looking through the drawer where we keep our tips. And I realized they were all different. Then I went to the ultrdent website and found out they are all used for different things. Who knew?

Cervical terminations in fixed prosthesis and dental bridges
The 4 fundamental criteria for successful margins are:
• Enough strength
Proper contour
• Tolerant tissue surface
Marginal adaptation acceptable
A dental bridge is a fixed partial denture that is used to replace one or more missing teeth by joining an artificial tooth definitively to an adjacent tooth.
A bridge consists of several components to make it functional.
An abutment is any tooth, root or implant which, gives attachment and support to the fixed partial denture.
A pontic is the artificial tooth that replaces a missing tooth in a fixed partial denture. Pontics are attached to the retainers.
All forces acting on the pontic are transferred to the abutment through the retainers.
Connectors are the connection that exists between the pontic and retainer. They may be rigid or non-rigid.
In general, a fixed bridge needs a metal support for strength. The veneer coating may be acrylic composite, or ceramic. Newer ceramic materials, including alumina, leucite, and zirconium, have increased strength that in some cases may eliminate the metal substructure.
