Benefits

Angelus Reforpost fiber glass - Retentive shape, parallel intraradicular post with conical tip.

High retentiveness

The cylindrical, parallel shape and tapered apex of the Glass Fiber Reforpost make them very retentive. The additional circumferential mechanical retentions of the posts increase the area for adhesion of the cement.

Less wear on the tooth structure

The use of Glass Fiber Reforpost in combination with the techniques of adhesive cementation allows for a smaller removal of dental structure, without the need for removal of intraradicular or coronal retentive areas. The tapered apical portion of the post also provides for less wear of dentin in the apical region.

• Saves clinical time and decreases lab costs

Time and cost saving

The technique of making prosthesis with pre-fabricated Fiber/Metal posts allows for creation of the post/core in a single session, eliminating steps and laboratory costs

Reforpost Metallic - Passive tapered intraradicular post system

Reforpost Metal - Surface texture

Angelus Metal post serrated or roughened surface is more retentive than a smooth one. Controlled grooving of the post and root canal  also increases the retention of the post

Reforpost Metal- Passive post system

It must be cemented passively. Active Screwable posts are harmful to the dental structures

Superior retention is observed in active THREADED POST, but it exerts a greater amount of stress on the remaining tooth structure  which increase the potential for root fracture.

Luting agents for post cementation

Currently there are 3 types of cement available for post cementation Resin cements, GIC  & zinc phosphate.

Self cure resin cement is the material of choice for post cementation as it has highest compressive strength along with negligible solubility. GIC bonds chemically with the dentin and is not technique sensitive. The most traditional of all cements is zinc phosphate, which has adequate physical properties, economic and easy to use as of which it remains as  choice of material  for post cementation for around decades.

Factors affecting retention of post

• Post space preparation 
• Luting Agent
• Post surface Texture
• Post Diameter
• Post Length

Benefits

• Saves clinical time and decreases lab costs
• Easy to use
• Easy to adapt
• No generation of stresses
• Excellent retention for the cement

Time and cost saving

The technique of making prosthesis with pre-fabricated Fiber/Metal posts allows for creation of the post/core in a single session, eliminating steps and laboratory costs

Avue Aurum - Gold Heat Treated Endo Rotary File System

Enhanced Cuttability

Convex Triangular Cross Section with 3 Cutting Edges reduce rotation friction between blade and dentine to improve cutting action. The decrease in torsional load helps to improve safety.

Improved Efficacy Due To Ease of Debris Removal

Progressive pitch makes more space for the debris which in turn push them upwards.

The higher the pitch or fewer turns the instrument has, the more flexible it will be, but in turn, the helical angle will decrease, and the file will have less cutting capacity, so, it will need more rotations to be effective.

Safe-Higher Fracture Resistance & Longer Service Life

Post machining gold heat treatment produces a better arrangement of the crystal structure which strengthen the files.

Eliminate Procedural Errors

The non-cutting tip design helps eliminate procedural error such as ledge formation transportation and perforations particularly in curved canals. One of the benefits of a progressively tapered shaping file is that each instrument engages a smaller zone of dentin, which reduces torsional loads, file fatigue and the potential for breakage

Flexible-Excellent Resistance to Cyclic Fatigue

Cyclic fatigue occurs when the instrument does not bind in the canal but rotates freely in a curvature whilst being subjected to repeated cycles of tension and compression, which disintegrates its structure and consequently leads to fracture.

Our Advanced design makes the file 200% more flexible. This allows superior resistance to cyclic fatigue which is the most common cause of file separation.

Better Adaption to Root Canal Curvatures

Controlled Memory Nickel Titanium wires offer remarkable memory-free property which allows the instrument to adapt to root canal curvatures and minimizes undesirable lateral. The Super elasticity of Niti rotary instruments provides improved access to curved root canals during the chemomechanical preparation, leading to their successful and extensive application in the clinical practice

Medium Body Addition Silicone Impression Material for single step impression.

Avuegum Monophase: Hydrophilic vinyl polysiloxane impression material used as one step impression material for implant impressions, edentulous, Crown & bridge  impressions.

AvueGum Mono acts both as tray material & wash impression material

The flow or viscosity of an impression material is dependent on the filler content. There are four basic categories: low (syringe or wash material), medium (one-step monophasic material), high (tray material), and very high (putty material)

AvueGum Mono has Excellent flow properties

AvueGum Medium body captures fine details for precise impressions it is stable as tray material and once prssure is applied will turned in low viscisity material.

Better initial hydrophilicity among all viscosities

It allows for accurate, void-free impressions even in moist conditions.AvueGum low contact angle along with tooth surface helps ensure an accurate impression in the presence of Saliva/GCF

Excellent hydrophilicity and outstanding thixotropy during processing and high final hardness after setting, the medium-viscosity material satisfies the requirements for perfect monophase impressions.

Helps get an accurate impression in a single step

This helps in reducing the need for costly adjustments, remakes and retakes.

Avuegum Monophase Impression material improves both, wettability on the tooth surface and model detail reproduction.

AvueGum Light body/Medium body shows thixotropic characteristics

Rheological characteristics making single step/putty wash impression more accurate. As AvueGum material shows shear thinning while applying pressure making it stable at first and flowable under pressure which is very important for a medium body impression material

The ability to record the tooth preparation accurately during the impression stage is critical for producing well-fitting crowns and bridges.

Shows Shear thinning characteristics

Viscosity is important when subgingival margins are to be captured. The ability of the impression material to reach the base of the sulcus is not only dependent on the viscosity but also the width of the sulcus. A wide sulcus allows for greater flow and thickness, which increases tear strength. Whichever method of sulcus preparation (mechanical, chemical, or surgical) is employed, it is critical that sufficient space is provided.Its shear thining property helps to incease its flow

Impression exhibits good dimensional stability

Stability and accuracy are necessary to record the fine details of hard and tissues and obtain biologically, mechanically, functionally, and esthetically acceptable restorations.

Addition polyvinyl siloxane impression materials have four types of viscosity to suit different needs.The medium body is commonly used as a monophase material or single-viscosity technique during crown and bridge work or for dentures.

Features

• Thixotropic characterstics and high tear strength.
• Uncompromised physical properties to capture accurate impressions.
• Excellent  surface detail reproduction.
• Dimensionally stable VPS chemistry to have distortion-free impression.
• Decrease in Viscosity with Increasing Shear-thinning
• Exceptional Hydrophilicity for its superb performance in the presence of moisture

Interactions

• Avoid contact between the impression material and latex gloves, Skin secretion because these inhibit the setting process.
• Avoid contact with retraction solutions, as residues of retraction solutions can delay the setting time.
• Do not mix Avuegum MONO with condensation silicone or polyether impression materials.

Addition Silicone impression material

Light Body Impression Materials are also known as hydrophilic vinyl polysiloxane impression materials. They are mainly used for the fabrication of crowns and bridges, denture impressions, and precise detailing of duplication of models. AvueGum Putty/Light Body is an impression material which gives detailed accuracy & excellent margins which the most important requirement of any restoration or prosthesis. 

Clinically, Improved hydrophilicity of AvueGum

Results in better wettability of the tooth surfaces, and performance in a moist environment offer better-than-ever precision.

Hydrophilicity, or contact angle, is most important when the material is being dispensed intraorally. AvueGum low contact angle along with tooth surface helps ensure an accurate impression in the presence of Saliva/GCF

High tear strength of AvueGum

Help to reduce the risk that the impression material tears off upon mouth removal. Another essential aspect for clinical success: The impression material has to withstand all the forces it is exposed to upon removal from the mouth. AvueGum impressions are rigid enough to withstand all the compression forces

Impressions of AvueGum are Dimensionally stable

 Distortions can be the reason for poorly fitting resorations. They usually are not known until the final restoration is ready for seating.AvueGum is dimensionally stable showing a minimum amount of shrinkage 

AvueGum Light body/Medium body shows thixotropic characteristics

Rheological characteristics making single step/putty wash impression more accurate. As AvueGum material shows shear thinning while applying pressure making it stable at first and flowable under pressure which is very important for a medium body

The impression is stable and can be cast even after one month 

AvueGum impression can be poured multiple times without jeopardising the accuracy accuracy of  impression material

AvueGum Putty Impression Material has high filler loading.

It is often combined with a AvueGum Light body during the impression procedure, known as the putty-wash technique, and is commonly used for dental impressions.

Impression techniques for Putty/Lightbody

Two techniques—one-stage or two-stage procedures—can be used when taking impressions with AvueGum light body and putty. For one-stage procedures, the wash material is syringed on the prepared tooth, and then the unset putty is seated over the light body material. AvueGum Putty Impression Material is very soft making it possible to capture margins in wash material as it is not pushed by its very heavy body consistency

For two-stage procedures, the initial putty impression is made and allowed to set, and then it is subsequently relined with wash materials,As per certain studies, two step impressions are better as all the details are captured in light body

Features of AvueGum Putty/Light body

• A firmly fixed material to allow tray support, yet flexible enough for easy removal.
• Easily mixed to Homogenous & Bubble free consistency Optimized flow guarantees precise detail reproduction in every clinical condition.
• Stays where you want and flows on your demand.
• Thixotrophic – non slumpy. Stable as well as flowable.
• Excellent recovery after deformation from undercuts.
• Can be poured long after taking impression without loss of accuracy.
• High tear resistance

The light body has the lowest viscosity and is placed on hard and soft tissues to record accurate surface details of tooth preparations even in presence of moisture because of its Superior Hydrophilicity.

Avue Prep is a water soluble Ethylenediaminetetraacetic acid (EDTA) gel for root canal cleaning

Avueprep works by reacting with the mineral components of the hard tissues of the tooth. The chelating agent Avueprep softens the tissues, decalcifying the canal walls. It facilitates the mechanical preparation of the root canal and further removal of the smear layer, which opens dentin tubules

EDTA is a polyaminocarboxylic acid and a colorless, water-soluble solid. It is widely used to dissolve lime scale. Its usefulness arises because of its role as a hexadentate ligand and chelating agent, i.e. its ability to sequester metal ions such as Ca²⁺ and Fe³⁺.

Indications of Avueprep EDTA with carbamide peroxide:

• Chelating (calcium binding) agent react with minerlized component of tooth.
• Removal of the smear layer which is produced during instrumentation.
• For chemical and mechanical cleaning of the root canal.
• Shaping of the root canal via using rotary or hand files.
• To be used with sodium hypochlorite as carbamide peroxide helps to produce nascent oxygen molecules when used with sodium hypochlorite

Smear layer removal:

The use of 15% -17%EDTA resulted in the greatest concentration of calcium ions compared with other chelating agents. Avueprep/Avueprep+ were the most efficient solution for removal of smear layer.

Antimicrobial activity

The antibacterial activity of Avueprep is due to the chelation of cations from the outer membrane of bacteria.

Effects on Dentin microhardness:

it reduce the root dentine microhardness, whereby the greatest differences are to be found in dentine immediately adjacent to the root canal lumen. After 3 min, Avueprep produced a greater reduction in microhardness.

Positively affect adhesion of root canal sealer:

Treating dentine with a combination of NaOCl and  EDTA produced stronger adhesion of resin based sealer compared to NaOCl alone.

Avueprep is Biocompatible

It has been proven that even if EDTA is forced through the apical foramen into the periapical tissues, no periapical tissue damage could be detected after 14 months. Furthermore, that placement of EDTA for 28 days after pulpotomy produced no pulpal tissue necrosis. However, changes in macrophage activity can cause the inflammatory reaction to be more easily initiated, but reduced capacity of phagocytosis can result. Furthermore, EDTA improves plasma extravasation and mediator action. 

Can remove calcium hydroxide while using Avueprep

It has been revealed that using Avueprep or NaOCl alone as irrigants did not remove calcium hydroxide from the root canal, but combining these two irrigants with hand instrumentation improved the effectiveness of the removal.
