Specification

TITLE OF THE INVENTION
"Universal and Modular Silicone Impression tray for Pediatric Dental Procedures."
FIELD OF THE INVENTION
The invention relates to dental impression trays specifically in the field of Paediatric
dentistry. The primary focus of this industry is the diagnosis, treatment, and maintenance of
dental health in children. To meet the specific anatomical and behavioural needs ofpaediatric
patients, specialized equipment is needed.
Relevance:
Precise impressions are essential for several processes in paediatric dentistry, such as the
fabrication of crowns, band and loops, orthodontic appliances, and other dental restorations.
Conventional impression trays may not offer the flexibility required for a wide range of arch
shapes and sizes, and they are frequently uncomfortable and painful for younger patients.
The universal sectional impression tray made of medical-grade silicone offers significant
advantages, including:
Comfort and Safety: The silicone material makes the tray safe to use on young patients,
reducing the possibility of discomfort or allergic responses. This is crucial in a vulnerable
population.
Flexibility: The lock and key mechanism makes it simple to attach and remove the tray,
giving dentists the opportunity to modify it to suit their particular clinical requirements. This
includes partial impressions for crown and loop preparations as well as whole arch
. .
ImpressiOns.
Better Results in Paediatric Dental Care: The invention guarantees that dental professionals
can get high levels of precision by accommodating both sectional and whole arch . .
ImpressiOns.
Optimized Workflow: The modular design streamlines the process of capturing impressions,
cutting down on chair time and experience for both the dentist and the young patient.
BACKGROUND
Accurate dental impressions are necessary in paediatric dentistry for a variety of treatments
such as restorations, orthodontics, and surgery planning. However, traditional dental
impression trays frequently fail to fulfil the unique demands of young patients. Many
standard trays are inflexible and do not fit well to the specific architecture of children's
mouths, resulting in discomfort and difficulties making accurate impressions. Standard trays,
which are normally developed for adults, have limited adaptability to the varying arch forms·
and sizes present in children, necessitating the use of multiple trays for different conditions,
increasing complexity and decreasing efficiency. Furthermore, standard trays are frequently
disposable_, adding to waste and expenses, whereas reusable solutions necessitate timeconsuming
cleaning and sterilization procedures that may not remove cross-contamination
tssues.
Existing methods struggle with customisation and handling since most trays lack paediatricspecific
designs, resulting in insufficient comfort and efficacy. The lack of modularity hinders
easy customization for sectional impressions, and typical materials, such as hard plastics,
might aggravate discomfort and increase patient anxiety. The time necessary to transfer
between trays might cause treatment delays, which have a detrimental influence on both
patient satisfaction and practice efficiency. The universal sectional imprint tray, manufactured
of silicone and equipped with a key and lock mechanism, tackles these issues by increasing
comfort, adaptability, and workflow efficiency in paediatric dentistry, eventually improving
the quality of care for young patients.
SUMMARY
The universal sectional imprint tray is a breakthrough instrument for paediatric dentistry,
made from medical-grade silicone to assure young patients' safety and comfort. This
innovative tray has a key and lock mechanism that allows for simple detachment and
attachment to fit sectional and full arch impressions.
The major goal of this invention is to improve the impression-taking process for dental
procedures including crown and·loop preparations, resulting in more accurate and
reliable results while reducing discomfort. Its primary benefits include improved flexibility to
diverse arch shapes, decreased waste due to its reusable construction, and higher workflow
efficiency, which allows dentists to swiftly tailor the tray for unique patient needs.
What makes this invention novel is its unique combination of flexibility and modularity,
which addresses the specific issues encountered in paediatric dentistry. This impression tray
improves patient experience and clinical outcomes by providing a comfortable, user-friendly
solution customized to youngsters, making it a great addition to dental practices.
DETAILED DESCRIPTION OF THE DIAGRAM
Figure 1 & 2 illustrates the universal and modular silicone dental impression tray designed
specifically for paediatric patients. The tray comprises the following components:
I. Main Tray Body (1):
The tray body is made of medical-grade silicone, ergonomically designed for
paediatric dental arches. It can be used for both full mouth impressi~:ms and sectional
. .
1mpresswns.
2. Retention Holes (2):
Multiple retention holes ensure secure mechanical interlocking of the impression
material.
3. Key and Lock System (3): .
The tray features a unique key and lock system, with a key (3a) and lock grooves (3b ),
allowing the attachment of interchangeable sections for sectional or full mouth
impressions.
4. Interchangeable Sections (4):
Modular sections (4a,4b,4c) are anatomically contoured for specific regions of the
dental arch, and they attach seamlessly to the main tray via the key and lock system
(3).
5. Removable Palatal Attachment (4c):
The· tray includes a detachable palatal attachment (4c), which can be attached to
convert the tray into a maxillary tray or detached to function as a mandibular tray. The
attachment fits securely into the main tray body using the key and lock system (3),
and its removal allows the tray to adapt seamlessly for mandibular impressions. This
feature enhances the tray's. versatility, allowing it to serve dual purposes without
requiring separate trays for upper and lower arches.
6. Handle (5):
A centrally located handle allows precise control during tray placement and removal
