Intended Use
The Lapdoc navigation system is a computerized navigational system intended to provide assistance in both the preoperative planning and the intra-operative surgical phases of dental implantation surgery. The system provides precise navigational guidance of surgical instruments such as a dental bur, with regard to the pre-operative planning in the dental implantation procedure.
Device Description
The Lapdoc System is a computer based assistance system for dental implantologists. It supports surgeons during planning and execution phase of dental implant procedures by providing highly precise quiding assistance during the implantation process within the human jaw. The systems supports the surgical implantation process by providing visual guidance for position and orienting of a dental bur relative to a planned implant position. The Lapdoc system is designed to support clinicians by decreasing complication rates of surgical interventions in the field of dental implantology. Using the system will allow precise orientation of the surgeon within the human jaw both in the medical image model of the jaw during the planning phase as well as in real anatomy during the execution phase. This is achieved by objective measuring the spatial positions of surgical instruments and the patients anatomy. Based on three dimensional medical image data, the surgeon plans an intervention by virtually placing models of implants within the graphical depiction (of the medical image set) of the jaw. The surgeon views and interprets the medical images which are graphically augmented with the computer models of the implants. It is further possible to manually mark the outlines of sensitive anatomical structures (i.e. nerves) within the medical images. To perfectly understand the geometric dimensions of the patients anatomy and the later intervention, a three dimensional model is created from isodense surfaces in the CT images and displayed on the computer screen. Lapdoc uses the geometric information of the planned implants within the medical images to generate highly precise information to guide the surgeon's instrument directly to the intended implant position and orientation. An optical measurement system consisting of an infrared-based stereo camera system and a set of two rigid structures (also known as rigid bodies or trackers) with attached reflectors is used to measure the spatial positions of the patient and the instruments. Therefore, the trackers are reproducible attached to the patient (using a dental splint) and to the surgical bur (using a cone nut connector). The stereo camera system comprises an internal position measurement processor and is connected to the Lapdoc computer. It senses the positions of the instruments and the patients tracker and communicates it to the Lapdoc computer. The computer calculates in real time the deviation between the actual and the desired (from the planning phase) transformation of the positions of both trackers. The actual bur position and the planned implant position and orientation are graphically displayed to the surgeon using a mini-display is placed within the vicinity of the surgeon and near the patient's mouth. The surgeon minimizes this deviation during the drill procedure by moving the bur in a way, that position and orientation of both the dental bur and planned implant are congruent. The system supports the surgeon by actieving a highly precise surgical outcome according to the planned scenario. Lapdoc system will graphically and audibly signal to the surgeon, if the plan is fulfilled and the surgical bur has reached its designated position and orientation. It will further warn the surgeon by reaching a minimal proximity value close to sensitive anatomical structures (i.e. nerves) and therefore avoids injury of such structures. Lapdoc is specifically designed to minimize the interaction between the user and the system. The application of the system follows simple ergonomic rules. The usage and working principle is easy to understand by the surgeon. The clinical workflow is not altered using Lapdoc. To describe the patients anatomy and the medical image model in one common coordinate system, it is necessary to perform an image registration process. This registration process comprises a navigation bow of known geometry and an algorithm to detect and measure the position of the navigation bow within the medical image data set. Lapdoc correlates the positions of the navigation bow within the image data with its measured spatial position. Since the navigation bow is attached reproducible to the patients jaw by click-snaping it onto the patient's teeth, positions on or within the patients anatomy can also be described within the medical image data set using the registration function.
More Information

Not Found

No
The description focuses on traditional computer-assisted navigation using optical tracking and image registration, without mentioning AI or ML algorithms for image analysis, planning, or guidance.

No
The device is a navigational system intended to provide assistance in both the preoperative planning and the intra-operative surgical phases of dental implantation surgery, providing guidance but not directly treating a disease or condition.

No
The device is a surgical navigation system providing guidance during dental implantation surgery, not a diagnostic device for identifying medical conditions.

No

The device description explicitly mentions and relies on hardware components such as an infrared-based stereo camera system, rigid structures (trackers) with reflectors, a dental splint, a cone nut connector, and a mini-display. These are integral to the device's function of measuring spatial positions and providing visual guidance.

Based on the provided information, the Lapdoc navigation system is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Lapdoc's Function: The Lapdoc system is a surgical navigation system. It uses medical imaging (CT scans) and optical tracking to guide surgical instruments during a procedure on the patient's body (the human jaw). It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states assistance in "preoperative planning and the intra-operative surgical phases of dental implantation surgery." This is a surgical guidance system, not a diagnostic test.

Therefore, the Lapdoc navigation system falls under the category of a surgical guidance or navigation device, not an in vitro diagnostic device.

SECTION E - 510(k) SUMMARY

The Lapdoc provides accurate guidance during the process of dental implantation. Surgical instruments are guided according to a pre-operative planning. The surgeon is assisted by avoiding the risk of causing damage to critical anatomical structures. Lapdoc is defined as a clinical assistance system, to support the surgeon during the implantation process with the ability of precise determination of position and orientation of surgical instruments within the patients anatomy. Lapdoc does not replace the human judgment. It is always the surgeons choice to define specific locations and angulations of the implant and to pursue this decision within the clinical treatment phase. Thus. the surgeon will not be released from his/her sole and ultimate clinical responsibility.

Intended use: The Lapdoc navigation system is a computerized navigational system intended to provide assistance in the preoperative planning and the intra-operative surgical phases of dental implantation surgery. The system provides precise navigational guidance of surgical instruments such as a dental bur, according to the preoperative planning in the dental implantation procedure.

Substantial Equivalence: Lapdoc shares technological and clinical features and an identical Intended use with different FDA-cleared tracking devices. The DenX-IGI (K023424), the Orthopilot (K003347), the VectorVision Cranial / ENT® (K023651) and the VectorVision 2 ® (K983831) system. Together, all this devices share some important features (not exclusively):

  • All devices serve as assistance systems by providing visual support during the freehand ﻪ positioning and orientation process of surgical instruments relative to the patients anatomy;
  • All devices measure positions of the human anatomy and surgical instruments by means of optical infrared-based measurement systems consisting of stereo camera systems;
  • All devices calculate the position and orientation of surgical instruments within the medical image data set by using the position measurement data;
  • All devices use sophisticated, yet easily understandable software tools to visualize medical ・ image data in different manners (slices and three dimensional models) and the positions and orientation of surgical instruments;
  • All devices reduce the risk of harming or damaging anatomical structures by visualization of ﻴﺮ ﺍﻟﻤﺴﺎﺣﺔ ﺍﻟﻤﺴﺘﻘﻠﺔ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍ such with respect to the actual positions of surgical tools;
  • All devices provide navigational accuracy of +/- 1,0 mm (overall system accuracy), which can not be achieved by brut human visual inspection.

The DenxIGP (K023424) system is a system for computer aided navigation of surgical instruments, whose purpose is to position a dental bur on the human jaw to optimally place and drill implant cavities. The system is based on the planning of such implant position within a three dimensional medical image data set (CT) and to pursue this position and angulation during the implantation process using an integrated position measurement device. The Orthopilot® (K003347) is

SECTION E - 510(k) SUMMARY

a computer aided system to navigate surgical instruments and to optimize the positions of cutting templates/guides for total knee replacement surgery and providing intra-operative measurements of bone alignment. The VectorVision Cranial / ENT® (K023651) and the VectorVision 2 °(K983831) are computer-aided systems for open or percutaneous surgery. They are indicated for any medical condition, where a reference to a rigid anatomical structure, such as the skull, a long bone or vertebra can be identified relative to a CT, MR or X-ray based model of anatomy.

Lapdoc and its predicate devices provide precise and accurate guidance of surgical tools and instruments within the patient's anatomy, near to organs or parts of it. Guidance is achieved by measuring positions of both the instruments and the anatomy and objective visualization of proportions and/or coherences of this spatial relationship.

All described devices do not intend to replace the surgeons expert knowledge and to release the clinicians responsibility.

The following navigation systems are used for the same body organs:

Systemorgan / body part / clinical application
DenX IGI® (K023424)Navigation in dental implantology
LapdocNavigation in dental implantology

Since the general principle of surgical navigation can be applied to any surgical field the following described navigation systems are used on different body organs:

Systemorgan / body part / clinical application
DenX IGI® (K023424)Navigation in dental implantology
Orthopilot® (K003347)Navigation for knee replacement surgery and bone alignment surgery
VectorVision 2 ® (K983831)Navigation in open/percutaneous surgery (skull/long-bones/vertebraes)
VectorVision Cranial / ENT®Navigation in open/percutaneous surgery (skull/long-bones/vertebraes)
(K023651)
LapdocNavigation in dental implantology

The effectiveness of all navigation support systems is based on their accuracy during the actual spatial guiding process for surgical instruments. The underlying principles of measuring positions of parts of the human anatomy and the positions of instruments, the registration of medical image data to the anatomy does not change with respect to the specific field of application remain the same. It can be assumed, that the safety and performance assumptions are not altered, when the principle of navigation is applied to the field of dental navigation. Summarized, the LapDoc-system is substantially equivalent to the declared predicate devices.
