Cavitypreparationsteps In restorative dentistry, the meticulous preparation of a tooth's cavity is paramount for the longevity and success of any fillingComplicated Cavities for Amalgam Among the various techniques employed, the distinction between box preparation and slot preparation (also referred to as slots or internal boxes) is crucial, particularly for Class II lesionsEffects of preparation designs and adhesive systems on While both aim to remove decay and provide retention for restorative materials, they differ significantly in their invasiveness and application作者：J Görücü·1997·被引用次数：23—In groups 1and4, thepreparationhad an extension through the occlusal groove, whereas the other four groups used a proximalslot(box-only)preparation. Understanding these differences is key for dental professionals to make informed decisions regarding optimal preparation strategiesThe steps of cavitypreparationoutlined include obtaining the outline formandinitial depth, primary resistanceandretention forms,andconvenience form.

Historically, the conventional box preparation has been a cornerstone of Class II restorations, especially for amalgamSteps Of Cavity Preparation | PPTX This method typically involves creating a rectangular or square cavity with a defined floor (pulpal) and four walls2003·被引用次数：11—Ultraconservativepreparationsrequire adhesive restorative materials with unique flowandfill prop- erties, as well as the ability to chemically bond to tooth  The primary resistance and retention forms are established through these walls, which resist displacement from tipping or lifting forcesInstead, there are two approaches. The "box-only", "Approximalslot",or"groove"preparation. This approaches the lesion directly from the marginal  For amalgam restorations, a box-like groove is prepared in the dentin, ideally 1Class II Amalgam Preparation0 to 1Class II Composite Slot Preparation· Class II Composite To create the proximal box, extend the preparation gingivally until the gingival contact breaks.5 mm deep, to enhance retentionSteps Of Cavity Preparation | PPTX The depth and design of this box are critical, with some studies indicating that a box-only preparation can provide adequate resistance form and retention for composite resin when used with proper etching and bonding agentsClass II Slot Preparation Techniques and Considerations However, the extent of the preparation can vary; some approaches, like the one discussed in research by J2025121—Box or slot preparations are gaining popularitydue to their conservative nature, preserving more tooth structure compared to traditional  G2 A laboratory study of permanent molars found that with etchingandbonding, thebox-onlypreparationprovided ad- equate resistance formandretention for composite resin.4. Extending thepreparationacross the oc- clusal surface did not provide greater resistance form than was achieved by. Görücü in 1997, involved an extension through the occlusal groove, while others utilized a proximal slot (box-only) preparationCavitypreparationsforslotrestorations with GIC are similar to amalgamslot preparations. A facialorlingual approach is used. Pulpal depth is 

In contrast, slot preparation represents a more conservative approach, often favored with the advent of adhesive restorative materialsSlots or internal boxes These are mainly used in amalgam restorations. They are 1.0 to 1.5 mm deep box like grooves prepared in dentin to increase the surface  This technique involves creating a more elongated, slot-like groove rather than a fully dimensional boxChanging concepts in Class I and II cavity preparation The box or slot preparations are gaining popularity due to their conservative nature, preserving more tooth structure compared to traditional methodsSlots or internal boxes These are mainly used in amalgam restorations. They are 1.0 to 1.5 mm deep box like grooves prepared in dentin to increase the surface  This is particularly relevant when dealing with proximal lesions where the occlusal surface may be pristine作者：PRA Restorations—However,slotsare less likely to create microfractures in the dentinandto perforate the toothorpenetrate into the pulp. ToothPreparationforSlot-Retained  In such cases, a slot preparation can be performed, directly approaching the lesion from the marginal ridge without necessitating an extensive occlusal preparationInstead, there are two approaches. The "box-only", "Approximalslot",or"groove"preparation. This approaches the lesion directly from the marginal  The concept of a "facial slot" or "lingual slot" also highlights the targeted nature of this approach, allowing for ultraconservative preparations that require specialized adhesive restorative materials with unique flow and fill properties, and the ability to chemically bond to the tooth structureInstead, there are two approaches. The "box-only", "Approximalslot",or"groove"preparation. This approaches the lesion directly from the marginal 

The choice between a box and a slot preparation is influenced by several factors, including the extent and location of the decay, the restorative material being used, and the desired level of tooth structure preservationWhen proximal lesions are to be restored with adhesive restorative materials, there is no need to create conventionalbox preparation. Instead, there are two approaches. 1. The external "trough", "slot",or"groove"preparation. This approaches the lesion  For instance, when restoring proximal lesions with adhesive materials, the need for a conventional box preparation is often eliminated2025121—Box or slot preparations are gaining popularitydue to their conservative nature, preserving more tooth structure compared to traditional  Instead, an external "trough," "slot," or "groove" preparation can be employedClass II Amalgam Preparation This approach directly accesses the lesion, minimizing the removal of healthy tooth tissueCavity preparation is essentially a box in form with floor (pulpal) and four walls. When the cavity is shallow, it is recommended to use resin composite since  Research has explored different preparations and modeling slot restoration geometry, including beveled preparations and beveled preparations with rounded corners, indicating an evolution in refining slot preparation techniquesPrepping for a class II composite - do you still connect the

Furthermore, the material choice significantly impacts the cavity preparationEffects of preparation designs and adhesive systems on While amalgam restorations often benefit from the inherent retentive features of a traditional box, composite resin restorations can be successfully managed with more conservative slot preparationsSteps Of Cavity Preparation | PPTX The use of resin composites has led to modifications, with some advocating for saucer-shaped boxes that are more favorable for lowering shrinkage strains on the bonded walls, a consideration not as critical with amalgamComplicated Cavities for Amalgam A Class II Composite Slot Preparation showcases this modern trend towards conservatism2025121—Box or slot preparations are gaining popularitydue to their conservative nature, preserving more tooth structure compared to traditional 

However, the success of slot preparations is not without its nuancesSlotpreps have had mixed results,andsuccess rates are influenced by a number of factors (type of bonding used, rubber dam usage, layering  Mixed results have been reported, with success rates influenced by various factors such as the type of bonding system used, the consistent application of a rubber dam, and the layering technique of the composite materialSlotpreps have had mixed results,andsuccess rates are influenced by a number of factors (type of bonding used, rubber dam usage, layering  While slots are less likely to create microfractures in the dentin and to perforate the tooth or penetrate into the pulp compared to more aggressive box preparations, meticulous technique is still paramountWhen proximal lesions are to be restored with adhesive restorative materials, there is no need to create conventionalbox preparation. Instead, there are two approaches. 1. The external "trough", "slot",or"groove"preparation. This approaches the lesion  The cavity preparation is essentially a box in form with floor (pulpal) and four walls, but when the cavity is shallow, the recommendation shifts towards using resin composite, often with conservative preparation designsClass II Amalgam Preparation

In conclusion, the evolution from traditional Class II box preparations to more conservative slot preparations reflects a broader movement in dentistry towards preserving healthy tooth structure without compromising the integrity and longevity of restorationsWhen proximal lesions are to be restored with adhesive restorative materials, there is no need to create conventionalbox preparation. Instead, there are two approaches. 1. The external "trough", "slot",or"groove"preparation. This approaches the lesion  Both techniques have their indications and contraindications, and a thorough understanding of their biomechanical principles, material interactions, and clinical applications is essential for achieving optimal patient outcomesThe steps of cavitypreparationoutlined include obtaining the outline formandinitial depth, primary resistanceandretention forms,andconvenience form.
