Dental Implant System - Tissue Level

Biodenta offers an innovative implant system with comprehensive solutions. The BST implant surface is achieved by an anodization process, which formulates a thicken titanium oxide layer. This roughened surface supports the final osseointegration of the implant. The final abutments can be securely placed in 8 different positions in a tight-fit 7° conical connection, intended to minimize micro-movements and optimizing the final prosthetic outcome. There are varieties of prosthetic options available, from stock abutment for single units to complex full-mouth restorations.

FE Analysis

This analysis dealt with the stress transference of the thread design of the Biodenta Dental Implant System (tissue level model of 3.5 mm endosteal diameter and 8 mm long thread area). All structural materials, cortical and cancellous bones as well as the implant were considered. The Poisson's Ratios were 0.35 for the implant and 0.3 for the bone structures respectively. To simulate the average masticatory force in a natural loading on the implant,, forces of 17.1N, 114.6N, and 23.4N were applied respectively in the lingual, the axial and the mesiodistal directions. The overall results showed the implant design had successfully prevented the transference of high stress to the surrounding bone. Owing to the geometry of the implant and the shape of the threads, the stress was dispersed distributed around the collar and the cancellous region.

Testing

Our well-designed implant, with a 7-degree internal conical and an octagonal shape joint, is tested according to ISO 14801. The implant has a standard abutment that is screwed together, and then mounted at a fixed 30-degree off-axis orientation, with a bone level 3 mm higher than the fixture surface.

A hemisphere cap, at the top of abutment, adds compressed force, which intersects the off-axis at a point 8 mm higher than bone level.

The fatigue force testing is started at 80% of static fracture strength and controlled in 15Hz sine wave. Failure was defined as permanent deformation of material yield, or fracture of any component of test samples. Testing is considered complete at 3 samples, of five million cycles, without failures.

Titanium has been widely used for artificial teeth roots replacement for decades. The integration of dental implants with the alveolar bone relies not only on mechanical force, but also on the biological surface bonding force, thus achieving integration.

To support osseointegration of Biodenta implants an anodization process occurs during the dental implant manufacturing. The BST surface consists of an amorphous titanium oxide layer that has surface roughness enhanced through open porosity. The osteoconduction process allows bone growth onto the surface. The Biodenta implant was designed with features that make it a good implant choice for many clinical applications. The design allows for high levels of initial stability and a reliable prosthetic platform for most restorative situations.

Biodenta implants are sterilised by gamma irradiation. Each implant is equipped with a sterile insertion tool and a sterile healing cap. The implants are delivered in a solid housing which well protects the implant. The housing offers a very practical handling option for the dentist.

Labeling

Conical connection
Conical connection is a feature for implants near the neck, which has a 7° cone connection for abutment, and healing cap matched to outer shape, providing good load transfer and minimal stress concentration. This 7° conical shape between abutment and implant provides an excellent mechanical joint, which passed 5 million cycles fatigue testing, as well as good sealing effects, which can prevent infection.

Octagonal Connection
The middle of the conical contains an octagonally shaped torque connection. When torque is applied to the implant, there will be surface contact instead of line contact, which we usually see in hexogen torque connections. The torque key cavity has 8 rounded lobes for minimal stress concentration within the minimal space. Precisely machined 8-lobe shape characteristics of implant and abutment provides excellent angle allocation of the prosthesis

Implant Procedures

Introduction

Each implant requires its individual surgical procedure which is well adjusted to the endosteal diameter and the shape of each implant. Please follow the Biodenta Surgical Guide in which all procedures are well explained and illustrated.

Planning

All efforts must be made to minimize damage to the host tissue, paying special attention to thermal and surgical trauma and to the elimination of contaminants and sources of infection. Please refer to the Biodenta Surgical Guide for details of the procedural precautions.

In the planning stage before surgery, it is important to determine the vertical dimension from the alveolar crest to the opposing dentition for the confirmation of the available space which will conform to the selected abutment and the final crown restoration. Each patient will have different dimensions and suitable abutment. Therefor, it should be carefully evaluated before surgery. The final prosthesis should be designed prior to the placement of the dental implant.

Implant Bed Preparation

Continuous irrigation should be used during the whole procedure with a cool, irrigating sterile saline to avoid excessive damage to the surrounding tissue and to prevent compromising osseointegration.

Avoid excessive pressure during preparation of the bone site. Please check the recommended speed and torque of the handpiece for surgical tools in the Biodenta Surgical Guide. Minimizing trauma to the bone and surrounding tissue with sharp instruments used enhances the potential for successful osseointegration.

Procedures

Surgical Instruments

Introduction

The Biodenta implant system does not require complex or complicated surgical instruments. The implant bed preparation and implant placement can be performed by only one surgical kit.

Surgical Kit

All the instruments are well positioned in the surgical kit. The upper area is reserved for the drills. A clear orientation and a coloured flow plan make the procedures very obvious to understand and follow.

The lower section covers all drivers and the adapters for handpiece and torque wrench. It is also equipped with a small container for bone graft material for sterilization and with a compact box for sterilization of abutments and healing caps prior to the operation.

Cleaning and Sterilisation

Introduction

All surgical instruments need to be disinfected, cleaned, dried and sterilised after use and before next application. Remove the remains of blood, secretion, tissue, or bone immediately. Do not allow them to dry. Contaminated instruments must be passed over for disinfecting immediately. After cleaning, all surgical instruments must be sterilised.

Preparing the instruments for autoclaving

After cleaning, disinfecting and drying, the instruments are sorted into the cleaned surgical kit. Completely enclose the kit in commercially available sterilisation wrap to maintain sterility.

Non-sterile devices

All non-sterile devices should be cleaned and / or sterilised prior to use, to eliminate contaminants and other sources of infection.

Surgical Instruments

The surgical instruments and other components are intended to support the achievement of surgery of implants and prosthetics. Autoclaving (135°C for 10 minutes or 121°C for 30 minutes) these tools in advance is essential.

Prosthetic Solutions

Introduction

The Biodenta implant system offers easy-to-use components to meet all of your restorative needs. You can follow the individual charts to identify the appropriate abutments for the type of restoration you are restoring: Cement-retained, screw-retained or overdenture restoration.

Platform Types

Abutment Selection

When selecting abutment, the dentist or lab technician needs to know the following:

Platform – The platform of the abutment must correspond to the implant platform.
Vertical Space – In addition to the height of the selected abutment, an additional 1.5 to 2.0 mm of space must be available over the prosthetic components to allow for casting and / or veneering material.
Angulation – The angulation of each implant will determine which abutment can be used, straight or angled, or whether a customized abutment is needed.
