As a solution, the proposed technique in this article “Custom Rings” is proven to be very effective. Historically, there were already similar techniques that can be confused with the “custom rings” technique, in 1981 form the book “textbook of Operative dentistry” by Baum/Phillips and Lund called “the non yielding matrix”, this technique had the objective of creating a super hard support for the matrix with acrylic in order to achieve extra contention for the amalgam condensation. The customizing material was applied only after the partial matrix was in place. Other historical techniques were found in the gold foil techniques by Tucker in order to contain the enormous amount of pressure applied during gold foil condensation, such techniques contemplated the use of acrylic resins, super hard impression compound materials, just to mention some. None of these techniques had the aim of copying the already natural and healthy teeth structures, all of these applied the material after the matrix were placed and not before, which is the main aim of this new development.

 

As a new development, our study group Styleitaliano developed the custom rings technique taking advantage of the simplest materials regarding wedges, rings and matrices in order to be able to personalize the ring embrasures to adapt the matrices in an anatomical and personalized way. The technique consists then on taking an impression with a photo-curing material (any light curing gingival material, block-out resin or flow composite) of the proximal embrasures of the teeth to restore and integrate them into the ring in order to be able to shutter perfectly wedge, matrices with a ring that will seal perfectly taking into advantage the anatomy of the healthy structures.

 

Indications

Class II composites, amalgams and gold foil restorations

Cases where intact anatomy of the impression area in mandatory

Teeth with medium and long clinical crowns

Any posterior cavity with a lack of axial wall where a matrix can be placed.

Big reconstructions where a matrix can be placed

 

Contraindications

Short and expulsive clinical crown.

Non intact anatomy found in the proximal embrasures.

Teeth where matrices cannot be placed.

When the previous situation is not convenient to be copied

 

Rules to follow for the custom rings to work:

- Impression must be carried out with the rubber dam and wedge on place (before cavity opening)

- Thin rings are advised (Original Palodent 3M, G-Rings with Standard Length or Composi-Tight® 3D Thin Tine G-Ring)

- Impression material ideally must be a gingival barrier, flowable composites are not advised because they are too stiff, but they are still useful.

- Sandblasting of the ring extremities are advised to have better resin fixation and less detachment problems.

- cavities must be filled up independently and matrix removed before next cavity is performed (in case of contiguous cavities) in order to achieve a very strong contact point.

 

Since its online publication, the custom rings technique is being taught in many universities and academies around the world. More than a 100 copies of the digital content in HD have been delivered to professors and lecturers who have requested it around the word.

The author wishes to thank Anna Salat and Jon Gurrea for their precious collaboration. The author wishes to express that the development of this technique was born during brainstorming with Dr. Walter Devoto and Prof. Angelo Putignano.

 

Preservation of a very small enamel ridge can be determining to the longevity of a restoration. Choosing the right time to be conservative – and when not to be – is of primary importance as we tend to see extremely conservative procedures that, paradoxically, can do more harm than good. This trick that I’m about to share is actually an old procedure that has been performed for more than 3 decades: it consists in preserving the thin remaining sound enamel below the gingival margin of the cavity after removing big decay. Thanks to adhesive procedures, it is easy to overcome this problem and respect the most delicate tissues remaining in our clean cavities.
Bulk fill materials are now-a-days a reality. In the posterior region they have proven to be the perfect material when used properly. This kind of materials entered the market almost a decade ago, with the skepticism of a big part of the dental community. Years of research are giving amazing results on the clinical performance of these new generation materials. Posterior restorations are never easy and most of the time is a challenge to avoid postoperative sensitivity and achieve a long term success. Most of the time these problems are triggered by a wrong use of photo curing materials in the cavity base. The characteristics of an ideal cavity base are the following - low or none toxicity - low or none contraction - low or none stress - high sealing power - high bonding strength - good polymerisation - physical resistance - mechanical performance - easy to place Conventional composites many times do not comply with these characteristics if they are used in increments of more than 2mm. Bulk fill composites have demonstrated to be an ideal base material, giving another advantage over regular composite and cavity bases such as glass ionomer or RMGIC, and of course comfortably surpassing conventional non-adhesive cements New bulk-fill composite materials are on the market for depths of up to 5 mm in an effort to simplify and improve placement of direct composite posterior restorations. Depth of cure for any dental composite is a critical issue, and especially for bulk-fill composites and research is proving that with encouraging results even in critical depth conditions. Bulkfill use for restorations under high occlusal load is subject to caution, a veneering material is highly advised, even if medium term results are encouraging, highly filled composites are still physically superior. 3D micro-computer tomography imaging has shown that the volumetric contraction and volumetric shrinkage are significative less than conventional composites, and with the correct use of adhesives this strategy is highly advisable to use this strategy. The bulk&body technique gives the following advantages. - Ideal material in cavity base - Ideal material in surface - Good polymerisation on deep layers - Low stress and contraction on the cavity bottom - Time saving - Good color blending The bulk and body technique, described in 2013 in www.styleitaliano.org follows the path of present and previous research and clinical experience of many authors. Stating thus, that this group has followed the natural logic that other authors have adopted with the use and advantages of these materials and does not claim any authorship rather than the Bulk&Body name.
